Definition: Sputum is matter that is expelled from the respiratory tract, such as mucus or phlegm, mixed with saliva, which can then be spat from the mouth. It is usually associated with air passages in diseased lungs, bronchi, or upper respiratory tract and also a case of pneumonia.Common types of sputum are mucus and phlegm.
A sputum sample is the name given to the mucus that is coughed up from the lower airways. It is usually used for microbiological investigations of respiratory infections.
The best sputum samples contain very little saliva, as this contaminates the sample with oral bacteria. This event is assessed by the clinical microbiologist by examining a Gram stain of the sputum. More than 25 squamous epithelial cells at low enlargement indicates salivary contamination.
When a sputum specimen is plated out, it is best to get the portion of the sample that most looks like pus onto the swab. If there is any blood in the sputum, this should also be on the swab.
Purulent Sputum is that containing, or consisting of, pus.
It is usually associated with air passages in diseased lungs, bronchi, or upper respiratory tract and also a case of pneumonia. It can be found to contain blood if a chronic cough is present, possibly from severe cases of tuberculosis. A sputum sample is the name given to the mucus that is coughed up from the lower airways.

1.Bloody (often found in tuberculosis) (Hemoptysis)
2.Rusty colored – usually caused by pneumococcal bacteria (in pneumonia)
3.Purulent – containing pus. The color can provide hints as to effective treatment in Chronic Bronchitis Patients:- ……………..I) a yellow-greenish (mucopurulent) color suggests that treatment with antibiotics can reduce symptoms. Green color is caused by Neutrophil Myeloperoxidase. …………….II)a white, milky, or opaque (mucoid) appearance often means that antibiotics will be ineffective in treating symptoms. (This information may correlate with the presence of bacterial or viral infections, though current research does not support that generalization.)
4.Foamy white – may come from obstruction or even Edema

Mucus is a slippery secretion produced by, and covering, mucous membranes. Mucous fluid is typically produced from mucous cells found in mucous glands. Mucous cells secrete products that are rich in glycoproteins and water. Mucous fluid may also originate from mixed glands, which contain both serous and mucous cells. It is a viscous colloid containing antiseptic enzymes (such as lysozyme), proteins such as lactoferrin, glycoproteins known as mucins that are produced by goblet cells in the mucous membranes and submucosal glands, immunoglobulins, and inorganic salts. This mucus serves to protect epithelial cells in the respiratory, gastrointestinal, urogenital, visual, and auditory systems in mammals; the epidermis in amphibians; and the gills in fish. A major function of this mucus is to protect against infectious agents such as fungi, bacteria and viruses. The average human body produces about a litre of mucus per day.

Bony fish, hagfish, snails, slugs and some other invertebrates also produce external mucus. In addition to serving a protective function against infectious agents, such mucus provides protection against toxins produced by predators, can facilitate movement and may play a role in communication.
In the respiratory system mucus aids in the protection of the lungs by trapping foreign particles that enter it, particularly through the nose, during normal breathing. “Phlegm” is a specialized term for mucus that is restricted to the respiratory tract, while the term “mucus” more globally describes secretions of the nasal passages.
Nasal mucus is produced by the nasal mucosa, and mucal tissues lining the airways (trachea, bronchus, bronchioles) is produced by specialized airway epithelial cells (goblet cells) and submucosal glands. Small particles such as dust, particulate pollutants, and allergens as well as infectious agents such as bacteria are caught in the viscous nasal or airway mucus and prevented from entering the system. This event along with the continual movement of the respiratory mucus layer toward the oropharynx, helps prevent foreign objects from entering the lungs during breathing. Additionally, mucus aids in moisturizing the inhaled air and prevents tissues such as the nasal and airway epithelia from drying out. Nasal and airway mucus is produced constitutively, with most of it swallowed unconsciously, even when it is dried.
Increased mucus production in the respiratory tract is a symptom of many common illnesses, such as the common cold and influenza. Similarly, hypersecretion of mucus can occur in inflammatory respiratory diseases such as respiratory allergies, asthma, and chronic bronchitis. The presence of mucus in the nose and throat is normal, but increased quantities can impede comfortable breathing and must be cleared by blowing the nose or expectorating phlegm from the throat. Tears are also a component of nasal mucus.
Diseases involving mucus:-
Generally nasal mucus is clear and thin, serving to filter air during inhalation. During times of infection, mucus can change colour to yellow or green either as a result of trapped bacteria, or due to the body’s reaction to viral infection.
In the case of bacterial infection, the bacterium becomes trapped in already clogged sinuses, breeding in the moist, nutrient-rich environment. Antibiotics may be used to treat the secondary infection in these cases, but will generally not help with the original cause.
In the case of a viral infection such as cold or flu, the first stage and also the last stage of the infection causes the production of a clear, thin mucus in the nose or back of the throat. As the body begins to react to the virus (generally one to three days), mucus thickens and may turn yellow or green. In viral infections, antibiotics will not be useful, and are a major avenue for misuse. Treatment is generally symptom-based; often it is sufficient to allow the immune system to fight off the virus over time.
Cystic fibrosis:….CLICK & SEE Cystic fibrosis is an inherited disease that affects the entire body, but symptoms begin mostly in the lungs with extremely viscous (thick) production of mucus which is difficult to expel.
Mucus as a medical symptom:
Increased mucus production in the upper respiratory tract is a symptom of many common ailments, such as the common cold. Nasal mucus may be removed by blowing the nose or by using traditional methods of nasal irrigation. Excess nasal mucus, as with a cold or allergies may be treated cautiously with decongestant medications. Excess mucus production in the bronchi and bronchioles, as may occur in asthma, bronchitis or influenza, may be treated with anti-inflammatory medications as a means of reducing the airway inflammation which triggers mucus over-production. Thickening of mucus as a “rebound” effect following overuse of decongestants may produce nasal or sinus drainage problems and circumstances that promote infection. Mucus with any color other than clear or white is generally an indicator of an infection of the nasal mucosa, the paranasal sinus or, if produced via a productive cough, of a lower respiratory tract infection.
Cold weather and mucus:……..CLICK & SEE
During cold weather, the cilia which normally sweep mucus away from the nostrils and towards the back of the throat (see respiratory epithelium) become sluggish or completely cease functioning. This results in mucus running down the nose and dripping (a runny nose). Mucus also thickens in cold weather; when an individual comes in from the cold, the mucus thaws and begins to run before the cilia begin to work again.
In the digestive system, mucus is used as a lubricant for materials which must pass over membranes, e.g., food passing down the esophagus. A layer of mucus along the inner walls of the stomach is vital to protect the cell linings of that organ from the highly acidic environment within it. The same protective layer of mucus is what comes out when you sneeze. Mucus does not digest in the intestinal tract. Mucus is also secreted from glands within the rectum due to stimulation of the mucous membrane within. You may click to see :-
Diseases Associated With Mucus in the Bowel Reproductive system:
In the female reproductive system, cervical mucus prevents infection. The consistency of cervical mucus varies depending on the stage of a woman’s menstrual cycle. At ovulation cervical mucus is clear, runny, and conducive to sperm; post-ovulation, mucus becomes thicker and is more likely to block sperm.
In the male reproductive system, the seminal vesicles contribute up to 100% of the total volume of the semen and contain mucus, amino acids, prostaglandins, vitamin C, and fructose as the main energy source for the sperm. You may click to see :What Is The Function Of The Pinocytic Vesicles
Sweating (Perspiration, transpiration, or diaphoresis) is the production of a fluid consisting primarily of water as well as various dissolved solids (chiefly chlorides), that is excreted by the sweat glands in the skin of mammals. Sweat contains the chemicals or odorants 2-methylphenol (o-cresol) and 4-methylphenol (p-cresol), as well as a small amount of urea. CLICK & SEE THE PICTURES
In humans, sweating is primarily a means of thermoregulation, although it has been proposed that components of male sweat can act as pheromonal cues. There is widespread belief that sweating, for example, in a sauna, helps the body to remove toxins, but the belief is without scientific support. Evaporation of sweat from the skin surface has a cooling effect due to the latent heat of evaporation of water. Hence, in hot weather, or when the individual’s muscles heat up due to exertion, more sweat is produced. Sweating is increased by nervousness and nausea and decreased by cold. Animals with few sweat glands, such as dogs, accomplish similar temperature regulation results by panting, which evaporates water from the moist lining of the oral cavity and pharynx. Primates and horses have armpits that sweat like those of humans. Although sweating is found in a wide variety of mammals, relatively few, such as humans and horses, produce large amounts of sweat in order to cool down..
A study has discovered that men, on average, start perspiring much more quickly than women, then twice as much when they are in the middle of exercising.
A man sweats after exercising.Sweating allows the body to regulate its temperature. Sweating is controlled from a center in the preoptic and anterior regions of the brain’s hypothalamus, where thermosensitive neurons are located. The heat-regulatory function of the hypothalamus is also affected by inputs from temperature receptors in the skin. High skin temperature reduces the hypothalamic set point for sweating and increases the gain of the hypothalamic feedback system in response to variations in core temperature. Overall, however, the sweating response to a rise in hypothalamic (‘core’) temperature is much larger than the response to the same increase in average skin temperature. The process of sweating decreases core temperature, whereas the process of evaporation decreases surface temperature.
There are two situations in which our nerves will stimulate sweat glands, making us sweat: during physical heat and emotional stress. In general, emotionally induced sweating is restricted to palms, soles, armpits, and sometimes the forehead, while physical heat-induced sweating occurs throughout the body.
Sweat is not pure water; it always contains a small amount (0.2–1%) of solute. When a person moves from a cold climate to a hot climate, adaptive changes occur in the sweating mechanisms of the person. This process is referred to as acclimatisation: the maximum rate of sweating increases and its solute composition decreases. The volume of water lost in sweat daily is highly variable, ranging from 100 to 8,000 mL/day. The solute loss can be as much as 350 mmol/day (or 90 mmol/day acclimatised) of sodium under the most extreme conditions. In a cool climate and in the absence of exercise, sodium loss can be very low (less than 5 mmols/day). Sodium concentration in sweat is 30-65 mmol/l, depending on the degree of acclimatisation.
Sweat contains mainly water. It also contains minerals, lactate, and urea. Mineral composition varies with the individual, their acclimatisation to heat, exercise and sweating, the particular stress source (exercise, sauna, etc.), the duration of sweating, and the composition of minerals in the body. An indication of the minerals content is sodium 0.9 gram/liter, potassium 0.2 gram/liter, calcium 0.015 gram/liter, magnesium 0.0013 gram/liter. Also many other trace elements are excreted in sweat, again an indication of their concentration is (although measurements can vary fifteenfold) zinc (0.4 mg/l), copper (0.3–0.8 mg/l), iron (1 mg/l), chromium (0.1 mg/l), nickel (0.05 mg/l), lead (0.05 mg/l). Probably many other less-abundant trace minerals leave the body through sweating with correspondingly lower concentrations. Some exogenous organic compounds make their way into sweat as exemplified by an unidentified odiferous “maple syrup” scented compound in several of the species in the mushroom genus Lactarius. In humans sweat is hypoosmotic relative to plasma
This writing might “stink” a little, but this information might serve as an important revelation to many particularly for elderly and persons with contineus stomac problem!
Human poops or stools, is the waste product of the human digestive system and varies significantly in appearance, depending on the state of the whole digestive system, influenced and found by diet and health.
Normally stools are semisolid, with a mucus coating. Small pieces of harder, less moist feces can sometimes be seen impacted on the distal (leading) end. This is a normal occurrence when a prior bowel movement is incomplete; and feces are returned from the rectum to the intestine, where water is absorbed.
Meconium (sometimes erroneously spelled merconium) is a newborn baby’s first feces. Human feces are a defining subject of humor.
Some persons have bloody stools on and off, usually accompanied by a sight tinch of discomfort. Many times, this doesn’t appear as a threat or danger to them as they often regard it as constipation though they may be passionate lover of fruits and vegetables. This might go on for some time until one day, bloody stools became really “bloody” and the pain became increasingly painful. Alarmed and paranoid, they call their dear ones who will recommend to see the doctor over at his or her clinic.
Now let us see What Does an Ideal Bowel Movement Look Like?
Alternative practitioners often ask clients about their stool as part of their assessment. Find out what normal stool should look like, and learn about the causes of green stool, pale stool, yellow stool, blood in stool, mucus in stool, pencil thin stool, infrequent stool, and more.
What Does an Ideal [amazon_textlink asin=’B001U1UKOO’ text=’Bowel Movement’ template=’ProductLink’ store=’finmeacur-20′ marketplace=’US’ link_id=’5c1f8c56-ee7e-11e6-87a4-8d88514c5f8b’]
An ideal bowel movement is medium brown, the color of plain cardboard. It leaves the body easily with no straining or discomfort. It should have the consistency of toothpaste, and be approximately 4 to 8 inches long. Stool should enter the water smoothly and slowly fall once it reaches the water. There should be little gas or odor.
Stool That Sinks Quickly
Rapidly sinking stool can indicate that a person isn’t eating enough fiber-rich foods, such as vegetables, fruits, and whole grains, or drinking enough water. This stool is often dark because they have been sitting in the intestines for a prolonged time. Click to learn 5 tips to boost your water intake.
Stool that is pale or grey may be caused by insufficient bile output due to conditions such as cholecystitis, gallstones, giardia parasitic infection, hepatitis, chronic pancreatitis, or cirrhosis. Bile salts from the liver give stool its brownish color. If there is decreased bile output, stool is much lighter in color.
Other causes of pale stool is the use of antacids that contain aluminum hydroxide. Stool may also temporarily become pale after a barium enema test.
Pale stool may also be shiny or greasy, float, and be foul smelling, due to undigested fat in the stool (see soft and smelly stool).
Other symptoms of spleen qi deficiency are: easy bruising, mental fogginess, bloating, gas, loose stools, fatigue, poor appetite, loose stools with little odor, symptoms that worsen with stress, undigested food in the stools, and difficulty ending the bowel movement. Spleen qi deficiency can be brought on by stress and overwork.
Eating certain foods in excess is thought to worsen spleen qi deficiency. Offending foods include fried or greasy foods, dairy, raw fruits and vegetables, and cold drinks, all believed to cause “cold” and “dampness” in the body. Dietary treatment of spleen qi deficiency involves eating warm, cooked foods. Ginger tea and cinnamon tea are also warming.
Pencil thin stool can also be caused by a bowel obstruction. Benign rectal polyps, prostate enlargement, colon or prostate cancer are some of the conditions that can cause obstruction.
Yellow stool can indicate that food is passing through the digestive tract relatively quickly. Yellow stool can be found in people with GERD (gastroesophageal reflux disease). Symptoms of GERD include heartburn, chest pain, sore throat, chronic cough, and wheezing. Symptoms are usually worse when lying down or bending. Foods that can worsen GERD symptoms include peppermint, fatty foods, alcohol, coffee, and chocolate.
Yellow stool can also result from insuffient bile output. Bile salts from the liver gives stool its brownish color. When bile output is diminished, it often first appears as yellow stool. If there is a greater reduction in bile output, stool lose almost all of its color, becoming pale or grey.
If the onset is sudden, yellow stool can also be a sign of a bacterial infection in the intestines.
Yellowing of stool can be caused by an infection known as Giardiasis, which derives its name from Giardia, an anaerobic flagellated protozoan parasite that can cause severe and communicable yellow diarrhea. Another cause of yellowing is a condition known as Gilbert’s Syndrome. This condition is characterized by jaundice and hyperbilirubinemia when too much bilirubin is present in the circulating blood.
Stool that is almost black with a thick consistency may be caused by bleeding in the upper digestive tract. The most common medical conditions that cause dark, tar-like stool includes duodenal or gastric ulcer, esophageal varices, Mallory Weiss tear (which can be linked with alcoholism), and gastritis.
Certain foods, supplements, and medications can temporarily turn stool black. These include:
*Bismuth (e.g. Pepto bismol)
*Aspirin and NSAIDS (which can cause bleeding in the stomach)
*Dark foods such as black licorice and blueberries
Stool can be black due to the presence of red blood cells that have been in the intestines long enough to be broken down by digestive enzymes. This is known as melena (or melaena), and is typically due to bleeding in the upper digestive tract, such as from a bleeding peptic ulcer. The same color change (albeit harmless) can be observed after consuming foods that contain substantial proportion of animal bloods, such as Black pudding or Ti?t canh. The black color is caused by oxidation of the iron in the blood’s hemoglobin (haemoglobin). Black feces can also be caused by a number of medications, such as bismuth subsalicylate, and dietary iron supplements, or foods such as black liquorice, or blueberries. Hematochezia (also haemochezia or haematochezia) is similarly the passage of feces that are bright red due to the presence of undigested blood, either from lower in the digestive tract, or from a more active source in the upper digestive tract. Alcoholism can also provoke abnormalities in the path of blood throughout the body, including the passing of red-black stool.
Dark stool can also occur with constipation.
If you experience this type of stool, you should see your doctor as soon as possible.
Prussian blue, used in the treatment of radiation cesium and thallium poisoning, can turn the feces blue. Also, substantial consumption of products containing blue food dye (things such as blue koolaid or grape soda)
Bright Red Stool
When there is blood in stool, the color depends on where it is in the digestive tract. Blood from the upper part of the digestive tract, such as the stomach, will look dark by the time it reaches exits the body as a bowel movement. Blood that is bright or dark red, on the other hand, is more likely to come from the large intestine or rectum.
Eating beets can also temporarily turn stools and urine red.
Blood in stool doesn’t always appear bright red. Blood may be also present in stool but not visible, called “occult” blood. A test called the Fecal Occult Blood Test is used to detect hidden blood in stool.
A tarnished-silver or aluminum paint-like stool color characteristically results when biliary obstruction of any type (white stool) combines with gastrointestinal bleeding from any source (black stool). It can also suggest a carcinoma of the ampulla of Vater, which will result in gastrointestinal bleeding and biliary obstruction, resulting in silver stool.
Urine is a sterile, liquid by-product of the body that is secreted by the kidneys through a process called urination and excreted through the urethra. Cellular metabolism generates numerous by-products, many rich in nitrogen, that require elimination from the bloodstream. These by-products are eventually expelled from the body in a process known as micturition, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis. Amniotic fluid is closely related to urine, and can be analyzed by amniocentesis. A major component of urine is urea. Urea is commonly recognized as an effective antibacterial, antifungal and antiviral agent. Urine contains 95% water 2. 5% mixture of urea and 2. 5% is mineral salts, hormones and enzymes.
The kidney produces urine. The other main function of the kidney is to regulate fluid balance in the body. It performs this function by using a selective osmosis system. Basically, the way it works is that electrolytes (dissolved salts like sodium, potassium, calcium, carbonate, chloride) are pumped back into or out of urine and blood so that in the end,
just the right amounts of electrolyte and water exit the kidney blood vein. The rest ends up in urine. Interestingly, normal urine is sterile and has no bacteria.
Urine contains 95% water and 5% solids. More than 1000 different mineral salts and compounds are estimated to be in urine. So far, our
scientific community knows of about 200 elements. Some substances are: vitamins, amino acids, antibodies, enzymes, hormones, antigens, interleukins,
proteins, immunoglobulins, gastric secretory depressants, tolergens, immunogens, uric acid, urea, proteoses, directin, H-11 (a growth inhibitory
factor in human cancer), and urokinase. Believe it or not, scientists have know for years that urine is antibacterial, anti-protozoal, anti-fungal, anti-
viral, and anti-tuberculostatic! Composition
Exhaustive detailed description of the composition of human urine can be found in NASA Contractor Report No. NASA CR-1802, D. F. Putnam, July 1971. That report provided detailed chemical analyses for inorganic and organic constituents, methods of analysis, chemical and physical properties and its behavior during concentrative processes such as evaporation, distillation and other phisiochemical operations. Urine is an aqueous solution of greater than 95% water, with the remaining constituents, in order of decreasing concentration urea 9.3 g/l, chloride 1.87 g/l, sodium 1.17 g/l, potassium 0.750 g/l, creatinine 0.670 g/l and other dissolved ions, inorganic and organic compounds.
Urine is sterile until it reaches the urethra where the epithelial cells lining the urethra are colonized by facultatively anaerobic Gram negative rods and cocci.Subsequent to elimination from the body, urine can acquire strong odors due to bacterial action. Most noticeably, the asphyxiating ammonia is produced by breakdown of urea. Some diseases alter the quantity and consistency of the urine, such as sugar as a consequence of diabetes.
Urine is a transparent solution that can range from colorless to amber but is usually a pale yellow. Colorless urine indicates over-hydration, which is usually considered much healthier than dehydration(to some extent however over hydration can remove essential salts from the body). In the context of a drug test, it could indicate a potential attempt to avoid detection of illicit drugs in the bloodstream through over-hydration.
*Dark yellow urine is often indicative of dehydration.
*Yellowing/light orange may be caused by removal of excess B vitamins from the bloodstream.
*Certain medications such as rifampin and pyridium can cause orange urine.
*Bloody urine is termed hematuria, potentially a sign of a bladder infection or carcinoma.
*Dark orange to brown urine can be a symptom of jaundice, rhabdomyolysis, or Gilbert’s syndrome.
*Black or dark-colored urine is referred to as melanuria and may be caused by a melanoma.
*Fluorescent yellow / greenish urine may be caused by dietary supplemental vitamins, especially the B vitamins.
*Consumption of beets can cause urine to have a pinkish tint, and asparagus consumption can turn urine greenish.
*Reddish or brown urine may be caused by porphyria. Although again, the consumption of beets can cause the urine to have a harmless, temporary pink or reddish tint.
The smell of urine can be affected by the consumption of food. Eating asparagus is known to cause a strong odor in human urine. This is due to the body’s breakdown of asparagusic acid. Other foods (and beverages) that contribute to odor include curry, alcohol, coffee, turkey, and onion.
Turbid urine may be a symptom of a bacterial infection, but can also be due to crystallization of salts such as calcium phosphate.
The pH of urine is close to neutral but can normally vary between 4.4 and 8. In persons with hyperuricosuria, acidic urine can contribute to the formation of stones of uric acid in the kidneys, ureters, or bladder. Urine pH can be monitored by a physician or at home.
A diet high in citrus, vegetables, or dairy can increase urine pH (more basic). Some drugs also can increase urine pH, including acetazolamide, potassium citrate, and sodium bicarbonate.
A diet high in meat or cranberries can decrease urine pH (more acidic). Drugs that can decrease urine pH include ammonium chloride, chlorothiazide diuretics, and methenamine mandelate.
The amount of urine produced depends on numerous factors including state of hydration, activities, environmental factors, size, and health. In adult humans the average production is about 1 – 2 L per day. Producing too much or too little urine needs medical attention: Polyuria is a condition of excessive production of urine (> 2.5 L/day), in contrast to oliguria where < 400 mL are produced per day, or anuria with a production of < 100 mL per day.
Density or specific gravity
Normal urine density or specific gravity values vary between 1.003–1.035 (g·cm?3) , and any deviations may be associated with urinary disorders.
A cure of many diseses that you do by yourself with own urine they call it “THE WATER OF LIFE”. I know several people in India who lived long with very minimum sickness, they used to drink their urine once every day. Off hand, I vividly remember the name of Morarji Desai, who was once Indian Priminister(from1977 to 1979) and a great political leader, survived till his 99th. birthday, maintained very good health all along,used to drink a glass of his own uring everyday morning throughout his life.The urotherapist say drinking urine increases our auto immuno system and protects us from many diseases.Urotherapy is also known as urine therapy, urea therapy and auto-urotherapy.
