Document Summary
: - chylomicrons leave the intestinal cells into lacteals (lymphatic system) Eventually enter bloodstream via the thoracic duct joining the subclavian vein (venous circulation) Liver eventually breaks down the chylomicron and recombines the content into a lipoprotein; various types of lipoproteins, many factors determines type. Fat content in lacteals is visble following consumption of fatty meal. : - all gets into the duodenum through a common entry point. The common bile duct dumps in bile from the gallbladder and newly made from the liver. Meanwhile, the pancreatic secretions come in through the pancreatic duct. The liver synthesizes bile acids from cholesterol, used to help break up lipid droplets. : - ~30-40% of cho are already digested before reaching the stomach. Once food is swallowed, it arrives in stomach (ph = 2) The acids decrease the function of the amylase so cho digestion slows (starch digestion) : - nutrients moving from gi tract into the blood or lymph system.
