Document Summary
In the stomach, food is converted into chime through muscular forces in the stomach wall assisted by hcl (acid) that helps kill microorganisms and activates enzymes like pepsin and aids in protein breakdown. Buffers gastric acid to prevent damage to epithelium. The stomach does not digest itself (cid:271)e(cid:272)ause the pepsi(cid:374) is(cid:374)(cid:859)t a(cid:272)ti(cid:448)ated (cid:894)f(cid:396)o(cid:373) pepsi(cid:374)oge(cid:374)(cid:895) u(cid:374)til it is released into the lumen of the stomach (cid:374)o(cid:449) the(cid:396)e(cid:859)s a (cid:373)u(cid:272)osal (cid:271)a(cid:396)(cid:396)ie(cid:396) Here the pancreas is the main contributor of digestive enzymes. Gall bladder store bile produced by the liver. Duodenum release cck when fat is sensed. Cck stimulates contraction of the gall bladder. Amylase is secreted by the salivary glands and the pancreas. Serve deficiency or absence in lactase, resulting in impaired breakdown of lactose. Lactose passes into the colon, where 2 things can happen: degraded by bacteria, producing hydrogen and methane gas, non- degraded lactose ill draw water into the colon, producing diarrhea.
