Document Summary
Lecture 2b digestion, absorption & transportation (jan 11) Steady movement at a pace that permits completion of all digestive processes. Lubrication of food ease of passage & aid in digestive processes. Exercise allows people to do these better. Sphincter dysfunction: relatively common problem, can cause acid reflux, which can lead to cancer. Bile is not an enzyme but rather brings fat into suspension w/ water so that other enzymes can break them down. In pancreas: sodium bicarbonate to neutralize ph. Gastric juice: ph of 2 (stronger than vinegar) Vitamin and mineral absorption: most occurs in small intestine, large absorbs water & dissolved salts. Undigested residues: continue through gi tract (fibre which binds to minerals, bile, water ) Large intestine: fibre fermentation by bacteria producing water, gas & some small fragments of fat (short chain fatty acids for ex) Biotin, folate, pantothenic acid, riboflavin, vitamins b12, b6, & k.
