Defecate
Defecation (or defaecation) follows digestion and is the necessary biological process by which organisms eliminate a solid, semisolid, or liquid waste material known as feces (or faeces) from the digestive tract via the anus or cloaca. The act has a variety of names, ranging from the technical (e.g. bowel movement), to the common (like pooping or crapping), to the obscene ('' shitting''), to the euphemistic ("doing number two", "dropping a deuce" or "taking a dump"), to the juvenile ("going poo-poo" or "making doo-doo"). The topic, usually avoided in polite company, forms the basis of scatological humor. Humans expel feces with a frequency varying from a few times daily to a few times weekly. Waves of muscular contraction (known as ''peristalsis'') in the walls of the colon move fecal matter through the digestive tract towards the rectum. Flatus may also be expulsed. Undigested food may also be expelled within the feces, in a process called ''egestion''. When birds defeca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Defecation
Open defecation is the human practice of defecating outside ("in the open") rather than into a toilet. People may choose fields, bushes, forests, ditches, streets, canals, or other open spaces for defecation. They do so either because they do not have a toilet readily accessible or due to archaic traditional cultural practices. The practice is common where sanitation infrastructure and services are not available. Even if toilets are available, behavior change efforts may still be needed to promote the use of toilets. 'Open defecation free' (ODF) is a term used to describe communities that have shifted to using toilets instead of open defecation. This can happen, for example, after community-led total sanitation programs have been implemented. Open defecation can pollute the environment and cause health problems and diseases. High levels of open defecation are linked to high child mortality, poor nutrition, poverty, and large disparities between rich and poor. Ending open de ...

Urate
Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C5H4N4O3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. High blood concentrations of uric acid can lead to gout and are associated with other medical conditions, including diabetes and the formation of ammonium acid urate kidney stones. Chemistry Uric acid was first isolated from kidney stones in 1776 by Swedish chemist Carl Wilhelm Scheele. In 1882, the Ukrainian chemist Ivan Horbaczewski first synthesized uric acid by melting urea with glycine. Uric acid displays lactam–lactim tautomerism. Uric acid crystallizes in the lactam form, with computational chemistry also indicating that tautomer to be the most stable. Uric acid is a diprotic acid with p''K''a1 = 5.4 and p''K''a2 = 10.3. At physiological pH, urate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squat Toilet
A squat toilet (or squatting toilet) is a toilet used by Squatting defecation posture, squatting, rather than sitting defecation posture, sitting. This means that the posture for defecation and urination is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not. Squat toilets are used all over the world, but are particularly common in some Asian and African nations, as well as in some Muslim countries. In many of those countries, anal cleansing with water is also the cultural norm and easier to perform tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defecation Postures
Humans mostly use one of two types of defecation postures to defecate: squatting and sitting. People use the squatting postures when using squat toilets or when defecating in the open in the absence of toilets. The sitting posture on the other hand is used in toilets that have a pedestal or "throne", where users generally lean forward or sit at 90 degrees to a toilet seat. Sitting The sitting defecation posture involves sitting with hips and knees at approximately right angles, as on a chair. So-called "Western-style" flush toilets and also many types of dry toilets are designed to be used in a sitting posture. In Europe, America and other western countries most people are accustomed to sitting toilets, although this fashion has only been present for around 100 years. Sitting toilets only came into widespread use in Europe in the nineteenth century. Sitting toilets requires users to strain in an unnatural position. In the sitting position, the puborectalis muscle chokes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toilet
A toilet is a piece of sanitary hardware that collects human waste (urine and feces) and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as '' blackwater'' and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet. " Toilet" or "toilets" is also widely used for rooms containing only one or more toilets and hand-basins. Lavatory is an older word for toilet. The technolo ...

Diaper
A diaper (, North American English) or a nappy (British English, Australian English, Hiberno-English) is a type of underwear that allows the wearer to urinate or defecate without using a toilet, by absorbing or containing waste products to prevent soiling of outer clothing or the external environment. When diapers become wet or soiled, they require changing, generally by a second person such as a parent or caregiver. Failure to change a diaper on a sufficiently regular basis can result in skin problems around the area covered by the diaper. Diapers are made of cloth or synthetic disposable materials. Cloth diapers are composed of layers of fabric such as cotton, hemp, bamboo, microfiber, or even plastic fibers such as PLA or PU, and can be washed and reused multiple times. Disposable diapers contain absorbent chemicals and are thrown away after use. Diapers are primarily worn by infants, toddlers who are not yet toilet trained, and by children who experience bedwettin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toilet Training
Toilet training (also potty training or toilet learning) is the process of training someone, particularly a toddler or infant, to use the toilet for urination and defecation. Attitudes toward training in recent history have fluctuated substantially, and may vary across cultures and according to demographics. Many of the contemporary approaches to toilet training favor a behaviorism and cognitive psychology-based approach. Specific recommendations on techniques vary considerably, although a range of these are generally considered effective, and specific research on their comparative effectiveness is lacking. No single approach may be universally effective, either across learners or for the same learner across time, and trainers may need to adjust their techniques according to what is most effective in their situation. Training may begin shortly after birth in some cultures. However, in much of the developed world this occurs between the age of 18 months and two years, with the majo ...

Anal Hygiene
Anal hygiene refers to practices (anal cleansing) that are performed on the human anus, anus to maintain personal hygiene, usually immediately or shortly after defecation. Anal cleansing may also occur while showering or bathing. Post-defecation cleansing is rarely discussed academically, partly due to the social taboo surrounding it. The scientific objective of post-defecation cleansing is to prevent exposure to Pathogen, pathogens. The process of post-defecation cleansing involves washing the anus and inner part of the buttocks with water. Water-based cleansing typically involves either the use of running water from a handheld vessel and a hand for washing or the use of pressurized water through a jet device, such as a bidet. In either method, subsequent hand sanitization is essential to achieve the ultimate objectives of post-defecation cleansing. History Materials The Ancient Greece, ancient Greeks were known to use fragments of ceramic, known as ''Ostracon, pessoi'' ...

Constipation
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The Human feces, stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day. Constipation has many causes. Common causes include slow movement of stool within the colon, irritable bowel syndrome, and pelvic floor disorders. Underlying associated diseases include hypothyroidism, diabetes, Parkinson's disease, celiac disease, non-celiac gluten sensitivity, Vitamin B12 deficiency, vitamin B12 deficiency, colon cancer, diverticulitis, and inflammatory bowel disease.

Diarrhea
Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. What is diarrhea? How is it caused, treated and prevented? (see also script)The most common cause is an infection of the intestines due to a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea ...

Meconium
Meconium is the earliest stool of a mammalian infant resulting from defecation. Unlike later feces, meconium is composed of materials ingested during the time the infant spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile, and water. Meconium, unlike later feces, is viscous and sticky like tar – its color usually being a very dark olive green and it is almost odorless. When diluted in amniotic fluid, it may appear in various shades of green, brown, or yellow. It should be completely passed by the end of the first few days after birth, with the stools progressing toward yellow (digested milk). Clinical significance Meconium in amniotic fluid Meconium is normally retained in the infant's bowel until after birth, but sometimes it is expelled into the amniotic fluid prior to birth or during labor and delivery. The stained amniotic fluid is recognized by medical staff as a possible sign of fetal distress. Some post-dates pregnancies ...
