Please explain.arrow_forward
- List the three most important ways to increase the intestinal surface without increasing the length of the intestine (start with the largest):arrow_forwardWhen the duodenu is actively digesting food, the Sphincter of Oddi released both bile and pancreatic juice into the duodenum Between meals, when the Sphincter of Oddi is closed, an accessory pancreatic duct remains open, allowing a slow but continual flow of pancreatic juice into the duodenum between meals WHy must there be pancreatic juice in the duodenum even if no food is currently being digested? A- Even if there isnt chyme in the duodenum, stomahc acid might leak into the duodenum. the trypsin in pancreatic juice neutralizes that B- We eat a lot, so we're always digesting food in the duodenum C - the process of fat breakdown is slow, so lipids could stay in the duodenum for over a day, so we need a steady supply of pancreatic lipase. D- Even if there isn't chyme in the duodenum, stomach acid might leak into the duodenum. The bicarbonate in pancreatic juice neutralizes thatarrow_forwardDescribe the main actions in the mouth, stomach, small intestine, and large intestine during lipid digestion and absorption. Describe the substrate(s) and product(s) of each of the give major enzymes we discussed: lingual lipase, gastric lipase, pancreatic lipase, phospholipase A2, and carboxyl ester lipase. Describe emulsification of lipids. Why does this need to happen for digestion and absorption to occur? Describe how lipids are absorbed at the apical membrane. Describe lipid transport in the enterocyte. Describe lipid transport across the basolateral membrane and into circulation. Define the brain-gut axis and give examples of how lipids impact. Give examples of symptoms related to malabsorption of lipids. Give examples of diseases/conditions involving malabsorption of lipids.arrow_forward
