Dirt (or dirt ) is a solid or semi-solid food of non-digestible food in the small intestine. The bacteria in the colon further break down the material. Feces contain small amounts of metabolic waste products such as bacteria-modified bilirubin, and dead epithelial cells from the lining of the intestine.
Dirt is released through the anus or cloaca during a process called defecation.
Feces can be used as a fertilizer or soil conditioner on the farm. It can also be burned and used as a fuel source or dried and used as a construction material. Some drug use has been found. In case of human feces, stool transplant or fecal bacteriosis is being used. Urine and feces together are called excreta.

Characteristics
The distinctive odor of stool is due to bacterial action. Intestinal flora produce compounds such as indole, skatole, and thiols (sulfur-containing compounds), as well as hydrogen sulfide inorganic gases. It is the same compound that is responsible for the smell of flatulence. Consumption of food prepared with spices can cause ingested spices and add to the smell of impurities.
The perceived dirt smell has been hypothesized as a barrier for humans, because consuming or touching it can cause illness or infection. The human perception of smell can be contrasted by the non-human perception of the animal; for example, animals that eat dirt may be attracted by the smell.
Physiology
Dirt is released through the anus or cloaca during a process called defecation. This process requires pressure that can reach 100 mm Hg in humans and 450 mm Hg in penguins. The force required to repel dirt is generated through muscle contraction and gas buildup in the intestine, encouraging the sphincter to reduce the pressure above it and release the dirt.

Ecology
Once the animal has digested the ingredients, the waste is removed from its body as waste. Although it is lower in energy than the food from which it originates, the stool can retain a large amount of energy, often 50% of the original food. This means that out of all the food eaten, large amounts of energy are left to decompose the ecosystem. Many organisms eat dirt, from bacteria to fungi to insects like dung beetles, which can sense odors from a distance. Some may specialize in dirt, while others may eat other foods. Dirt not only serves as a basic food, but also as a supplement to the regular diet of some animals. This process is known as coprophagia, and occurs in a variety of animal species such as young elephants eating their mother's excrement to obtain essential intestinal flora, or by other animals such as dogs, rabbits, and monkeys.
Dirt and urine, which reflect ultraviolet light, is important for birds of prey such as kestrels, who can see the near ultraviolet and thus find their prey with their middens and territorial markers.
Seeds can also be found in the dirt. Animals that eat fruit are known as frugivores. The advantage to the plant in producing the fruit is that the animal will eat the fruit and unknowingly disperse the seed in doing so. This way of seed dispersion is very successful, because the seeds scattered around the base of the plant may not work and are often the target of heavy predation. Provided that the seed can hold the path through the digestive system, it not only may be far from the mother plant, but even provided with its own fertilizer.
Organisms that live from dead organic matter or detritus are known as detritivors, and play an important role in the ecosystem by recycling the organic material back into a simpler form that other plants and autotrophs can absorb once again. Cycling this material is known as the biogeochemical cycle. To keep the nutrients in the soil, it is important that the feces return to their home areas, which is not always the case in human societies where food can be transported from rural areas to urban populations and then droppings discharged into rivers or seas..
Human feces
Depending on the individual and the circumstances, humans may defecate several times a day, every day, or every two or three days. Extensive hardening that interferes with this routine for several days or more is called constipation.
The appearance of human feces varies according to diet and health. Usually it's semipadat, with a layer of mucus. The combination of bile and bilirubin, which comes from dead red blood cells, gives a distinctive brown color feces.
After meconium, the first stool is removed, the newborn's stool contains only bile, which gives it a yellow-green color. Breastfeeding infants give off soft, pale yellow, and do not smell bad enough; but once the baby begins to eat, and the body starts removing bilirubin from the dead red blood cells, the material acquires the familiar brown color.
At different times in their lives, humans will repel dirt from different colors and textures. The bench that passes through the intestine quickly will look greenish; Lack of bilirubin will make the stool look like clay.
Pets
Pets can be trained to use a litter box or wait to be allowed outside to defecate. Training can be done in several ways, especially depending on the species. An example is the training of crate for dogs. Some companies market cleaning products to pet owners whose pets have dirty carpets at home.
Use of animal waste
Fertilizer
Animal waste is often used as fertilizer; see guano and manure.
Energy source
Dry animal dung is burned and used as a fuel source in many countries around the world. Some animal waste, especially camels, bison, and cows, is a fuel source when it is dried.
Animals such as giant pandas and zebras have intestinal bacteria capable of producing biofuels. The bacterium, called Brocadia anammoxidans, can create hydrazine rocket fuel.
Koprolit and paleofeces
A koprolite is a fossilized faeces and is classified as a trace fossil. In paleontology they provide evidence about animal diets. They were first described by William Buckland in 1829. Prior to this they were known as "fossil fire cones" and "bezoar stones". They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Koprolit can be sized from several millimeters to more than 60 cm.
Palaeofeces are ancient human excrement, often found as part of archaeological excavations or surveys. The complete feces of the ancient people can be found in caves in dry climates and in other locations with appropriate preservation conditions. It was studied to determine the diet and health of the people who produced them through analysis of seeds, small bones, and parasitic eggs found in them. This stool may contain information about the person who issued the material as well as information about the material. They can also be chemically analyzed for more in-depth information on the individuals who excrete them, using lipid analysis and ancient DNA analysis. The level of success of DNA extraction that can be used is relatively high in paleofeces, making it more reliable than taking skeletal DNA.
The reason for this analysis is probably at all is because the digestive system is not fully efficient, in the sense that not all that passes through the digestive system is destroyed. Not every surviving material can be recognized, but part of it. Generally, this material is the best indicator that archaeologists can use to determine the ancient diet, since no other part of the archaeological record is so straightforward as an indicator.
A process that retains the feces in a way that can be analyzed then called the Maillard reaction. This reaction creates a sugar casing that keeps the dirt from the elements. To extract and analyze the information contained therein, researchers generally have to freeze the dirt and grind it into powder for analysis.
Other uses
Animal manure is sometimes used as cement to make adobe mudbrick huts, or even in throwing sports such as throwing cow throwing or throwing camel camel contest.
Kopi Luwak (pronounced ['kopi' lu.a?] ), or Luwak coffee, is coffee made from coffee that has been eaten by and through the digestive tract of Asian coconut civet ( Paradoxurus hermaphroditus ). The giant panda provides fertilizer for the world's most expensive green tea. In Malaysia, tea is made from dirt insect sticks that are given guava leaves.
In northern Thailand, elephants are used to digest coffee beans to make Black Ivory coffee, which is the most expensive coffee in the world.
Dog dung was used in the tanning process during the Victorian era. The collected dog dung, known as "pure", "puer", or "pewer", is mixed with water to form a substance known as "bate." Enzymes in dog feces help relax the fibrous structure from hiding before the final stage of tanning.
Elephants, hippos, koalas and pandas are born with sterile intestines, and require bacteria gained from eating their mother's excrement to digest plants.
Terminology
Dirt is a scientific terminology, while term stools are also commonly used in medical contexts. Beyond the scientific context, these terms are less common, with the most common layman's term being dirt (or dirt in the English language of North America). The term dirt is also commonly used, although it is widely considered vulgar or offensive. There are many other terms, see below.
Etymology
The word faeces is the plural of the Latin faex which means "dregs". In most English usage, there is no single form, making the word into tantum plurale; of the main dictionaries, only one that entered the variation of the plural agreement.
Synonyms
"Feces" is more widely used in biology and medicine than in any other field (reflecting the scientific tradition of classical Latin and New Latin)
- In hunting and tracking, terms like dirt , dirt , dirt , and dirt are usually used to refer to non-human animal feces
- In farms and farms, dirt is common.
- Dirt is a generic term that refers to human waste. For example, in medicine, to diagnose the presence or absence of medical conditions, stool samples are sometimes required for testing purposes.
- The term bowel movement (s) (with every movement of bowel movements) is also common in health care.
There are many synonyms in the informal register for feces, as is the case for urine. Many are euphemistic, everyday, or both; some are profane (like dirt ), whereas most belong primarily to speeches intended for children (such as dirt or dirt) or humor roughly (Like nonsense, dump, load and turd .).
Animal droppings
Animal waste often has a special name, for example:
- Animals are not human
- As bulk material - dirt
- One by one - dirt
- Cow
- Bulk material - cow dung
- Individual manure - beef pat, muffin pasture, etc.
- Deer (and formerly other minerals) - fewmets
- Wild carnivores - shit
- Otter - spraint
- Bird (individual) - dirt (also includes urine as uric acid white crystals)
- Seabirds or bats (big accumulations) - guano
- Herbivorous insects, such as caterpillars and leaf-beetles
- Earthworms, earthworms, etc. - worm worms (soil extruded at the soil surface)
- Filth when used as fertilizer (usually mixed with animal and urine base) - fertilizer
- Horses - horse shit, roadapple (before motor vehicles become common, horse shit is a big part of the garbage community needed to clear the road)
Society and culture
Disgusted feelings
In all human cultures, feces produce a variety of levels of aggravation, basic human emotions. Disgust is experienced primarily in relation to the sense of taste (both perceived or imagined) and, secondly to anything that causes the same feeling by the sense of smell, touch, or vision.
Social media
There's a poo emoji pile represented in Unicode as U 1F4A9 ? poo stack , called unchi or unhci-kun in Japan.
