Document Summary

Ingestion digestion absorption elimination: all animals are heterotrophs (getting energy from organic molecules that has been manufactured by some other organism) In animals, there are 4 stages of food processing- figure 41. 5. 4. throughout digestive tract, you will find sphincters a) b) ring-like, muscular valves regulates passage that control movements from one side of the tube to the other side: figure 41. 9- the human digestive system, before ingestion. 4: mucus acts as a lubricant b) in mucus are mucins (1) mucins are glycoproteins (a) help things move around (2) mucus also protects the lining of the mouth. 2. there are 3 divisions: duodenum (1st division) (1) where chemical digestion takes place, jejunum (2nd division) c) Absorption- most of the nutrients are going to be absorbed through the villi in the small intestine. Large intestine (= colon) (6th compartment: has a larger diameter than the si but actually shorter. Liver (7th compartment: has a strategic location in the body.
