Information about Bolus (digestion)
In digestion, a bolus (from Latin bolus, ball) is a round mass of organic matter moving through the digestive tract. A bolus is initially shaped through chewing and swallowing of food and maintained as peristalsis moves it through the intestines, eventually being released as feces. The term is also used in aerospace engineering, in order to define the characteristics of human feces, especially pertaining to devices for processing its defecation while in space or other flight environments.
A radio-frequency identification tag ingested by livestock is also referred to as a bolus. It remains in the stomach of the animal for its lifetime and emits a unique ID that can be used to track an animal.

gastrointestinal tract (GI tract), also called the digestive tract, or the alimentary canal, is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste.

Mastication or chewing is the process by which food is mashed and crushed by teeth. It is the first step of digestion and it increases the surface area of foods to allow more efficient break down by enzymes.

Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract. The word is derived from New Latin and comes from the Greek peristaltikos, peristaltic, from peristellein, "to wrap around," and stellein

In anatomy, the intestine is the segment of the alimentary canal extending from the stomach to the anus and, in humans and other mammals, consists of two segments, the small intestine and the large intestine.

Feces, faeces, or fæces (see spelling differences) is a waste product from an animal's digestive tract expelled through the anus (or cloaca) during defecation. The word faeces is the plural of the Latin word fæx meaning "dregs".

Human feces (also faeces — see spelling differences), also known as stools, vary significantly in appearance, depending on the state of the whole digestive system, influenced by diet and health. Normally they are semisolid, with mucus coating.

Defecation is the act or process by which organisms eliminate solid or semisolid waste material (feces) from the digestive tract via the anus. Humans expel feces anywhere from a few times daily to a few times weekly; sloths can go a week without expelling.
