Unformatted text preview: "regulation of release " - lipids in duodenum stimulate CCK to be released - CCK causes gall bladder smooth muscle to contract and causes sphincter of Oddi to relax - PNS ==> increased bile flow -> increased gallbladder contractions - SNS ==> decreased bile flow -> decreased gallbladder contractions - digestion and absorption are facilitated by peristalsis and segmentation. Digestion of fats (Figure 21-26)-Fat digestion starts in the mouth with lingual lipase , converting triglycerides into monoglycerides and free fatty acids (Figure 21-8) . -little digestion occurs in the stomach, although gastric lipase , which can work at low pH, is secreted by the chief cells (Figure 21-16) . -The pancreas secretes pancreatic lipase, that functions the same way as both lingual and gastric lipases, into the intestine. Bile, a non-enzyme secretion from the hepatocytes of the liver, is important for of fat digestion. The key components of bile for fat digestion are bile salts. Bile salts are the combination of steroid detergents and amino acids for fat digestion are bile salts....
