GENERAL HISTOLOGY

Detailed explanation-1: -Chyme or chymus (/kaɪm/; from Greek khymos, “juice") is the semi-fluid mass of partly digested food that is expelled by a person’s or an animal’s stomach, through the pyloric valve, into the duodenum (the beginning of the small intestine).

Detailed explanation-2: -After being stored and mixed with hydrochloric acid in the stomach for about 30 to 60 minutes, chyme slowly enters the duodenum through the pyloric sphincter.

Detailed explanation-3: -Chyme passes from the stomach into the duodenum. There it mixes with bile and pancreatic juices that further break down nutrients. Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients.

Detailed explanation-4: -The chyme is gradually pushed down the duodenum by peristaltic waves which flow down the length of the digestive tract. Most of the digestion of the protein, fats and carbohydrate in the chyme is done by the enzymes in the duodenum, before the resultant mixture is passed further into the small intestine.

Detailed explanation-5: -The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum. After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas.
