the sphincter that allows chyme to pass from the stomach into the small intestine is known as the
Chyme Chyme or chymus (/kaɪm/; from Greek χυμός khymos, "juice"[1][2]) is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum[3] (the beginning of the small intestine).
Small intestine The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the end absorption of food takes place. The small intestine has three distinct regions â€“ the duodenum, jejunum, and ileum. The duodenum is the shortest part of the small intestine and is where preparation for absorption begins. It also receives bile and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi. The primary function of the small intestine is the absorption of nutrients and minerals from food, using small finger-like protrusions called villi.[2]
