Document Summary

Chapter 3: digestion, absorption & transport: describe how gastrin, cholecystokinin, and secretin control stomach acidity, intestinal ph, bile release, and gi motility. Gastrin- secreted from stomach wall hydrochloric acid released to maintain acidic ph. Cholecystokinin- secreted from intestinal wall (gallbladder) bile secreted into duodenum (pancreas) bicarbonate secreted into small intestine to maintain slightly alkaline ph slows gi tract motility. The enzymes are made in an inactive form (zymogens) to keep the pancreas from digesting itself! The duct cell makes fluid that mixes with the zymogens to make pancreatic juice. The pancreatic juice flows from the acinar cells to the first part of the small intestine (duodenum): describe the impact of gallbladder removal on the ability to digest fats. Fat emulsification can continue even after a diseased gallbladder has been surgically removed because the liver can deliver bile directly to the small intestine. Describe the level of sweetness of glucose, galactose and fructose (i. e. mildly sweet, barely sweet or very sweet)
