Stomach Flashcards
Cardiac sphincter
Lower esophageal sphincter
Cells of gastric gland and their functions
Mucus cells(make mucus to protect stomach lining), parietal cells(secrete HCl), chief cells (Secrete pepsinogen)
Pyloric gland function
Secrete gastrin which enduces stomach to secrete HCl
Pyloric sphincter
Food leaves stomach through pyloric sphincter and enters duodenum of small intestine
sections if the small intestine
Duodenum, jejunum, ileum. Covered in villi which are covered by micro villi
Chyme
Mixture if HCl and the contents of stomach
Pancreatic juice
Mixture if several enzymes in a bicarbonate (basic) solution
Secretin
Hormone that causes pancreatic juice to be exuded from pancreas
Cholecystokinin CCK
Released by small intestine to signal gall bladder to release bile into duodenum. Signals in response to movement of chyme out of the stomach into the intestines
Enterogastrone
Slows movement if chyme to allow more time to digest fat after a fatty meal
Sections of large intestine
Cecum (contains appendix) , colon (absorbs water and salts), rectum(storage site for feces), anus (opening) anus has 2 openings-internal and external anal sphincters. (Internal is under involuntary control)
Chylomicrons
Triglycerides and esterified cholesterol molecules packaged into insoluble chylomicrons and enter lymphatic circulation through lacteals
