Detailed explanation-1: -chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid.
Detailed explanation-2: -Chyme is created from the ingested bolus through muscular contractions of the stomach, which mix food with the secretions of the stomach. Chyme passes from the stomach to the small intestine in short spurts and influences pancreatic secretions and the release of bile from the gall bladder and liver.
Detailed explanation-3: -Once food is semi-digested it is known as chyme and is passed through the pyloric sphincter, a ring of smooth muscle at the lower part of the stomach, by muscular contractions into the duodenum.
