Chyme has a low pH that is countered by the production of bile, which helps the further digestion of food. Chyme is part liquid and part solid: a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and small intestine during digestion. Chyme also contains cells from the mouth and esophagus that ...
Food in the GI tract is called a bolus (ball of food) from the mouth down to the stomach. After the stomach, the food is partially digested and semi-liquid, and is referred to as chyme . In the large intestine the remaining semi-solid substance is referred to as faeces.
In the human digestive system, a bolus (a small rounded mass of chewed up food) enters the stomach through the esophagus via the lower esophageal sphincter. The stomach releases proteases (protein-digesting enzymes such as pepsin ), and hydrochloric acid , which kills or inhibits bacteria and provides the acidic pH of 2 for the proteases to work.
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Upper and lower human gastrointestinal tract. The human gastrointestinal tract is around 9 metres (30 feet) long. Food digestion physiology varies between individuals and upon other factors such as the characteristics of the food and size of the meal, and the process of digestion normally takes between 24 and 72 hours.
This bolus from an albatross has several ingested flotsam items, including monofilament from fishing nets and a discarded toothbrush. Tern Island, French Frigate Shoals. In digestion, a bolus (from Latin bolus, "ball") is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing (which is largely an adaptation for plant-eating mammals).

A bezoar (/ ˈ b i z ɔː r / BEE-zor) is a mass often found trapped in the gastrointestinal system, [2] though it can occur in other locations. [3] [4] A pseudobezoar is an indigestible object introduced intentionally into the digestive system.
