gentle rippling peristaltic movements happen several minutes after food enters the stomach. They pass over the stomach every 15-25 seconds. They macerate food, mix it with secretions of the gastric glands and reduce it to a soupy liquid called chyme
a phenomenon where food reaches the pylorus, where each mixing wave periodically forces about 3ml of chyme into the duodenum through the pyloric sphincter.
powered by H+/K+ ATPases actively transport H+ into the lumen while bringing potassium ions into the cell.
the only protein digesting enzyme in the stomach which is secreted by chief cells
it splits the short chained triglycerids in fat molecules into fatty acids and monoglycerides.
a retroperitoneal gland. it lies posterior to the greater curvature of the stomach.
head of pancreas
is the extended portion of the organ near the curve of the duodenum
superior to and to the left of the head are the central body and tapering tail
pancreatic juices are secreted into this. It is the larger of two. it joins the common bile duct from the liver and gallbladder and enters the duodenum as a dilated common duct called hepatopancreatic ampulla
a dilated common duct that enters the duodenum from the liver gallbladder and pancreas
sphincter of the hepatopancreatic ampulla
the passage of pancreatic juices and bile through the hepatopancreatic ampulla into the small intestine is regulated by a mass of smooth muscle tissue called this
accessory duct or duct of santorini
leads from the pancreas and empties into the duodenum superior to the hepatopancreatic ampulla
clusters of glandular epithelial cells in the pancreas that constitute the exocrine portion of the organ
the cells within acini secrete a mixture of fluid and digestive enzymes
clusters of glandular epithelial cells that form the endocrine portion of the pancreas. These cells secrete hormones glucagon, insulin, somatostatin and pancreatic polypeptide
starch digesting enzyme in the pancreas
trypsin, chymotyrpsin, elastase, carboxypeptidase
protein digesting enzymes in the pancreas
the principal triglyceride digesting enzyme in adults
