Document Summary
41. 2: the main stages of food processing are ingestion, digestion, absorption, and elimination: four stages of food processing (f41. 7) Ingestion: food brought in through the mouth: digestion, mechanical breakdown physical breakdown of food, chemical breakdown digestive chemicals and enzymes breakdown food, absorption: small subunits transported out of digestive system, elimination: indigestive material expelled from body. Finishes digestion in small intestine: protein breaks down in stomach, absorption of nutrients (f41. 15, the small intestine is well adapted for absorption of nutrients, surface area is increased by numerous folds with finger-like projections (villi) and microvilli. 41. 4: evolutionary adaptations of vertebrate digestive systems are often associated with diet: digestive specializations (f41. 19) Fats small intestine: bile, produced by the liver and stored by the gall bladder, emulsifies fats in the small intestine. The liver is a component of the alimentary canal be separated within the tract: false, false.
