What are all the parts to the digestive system? - correct-answer -
How does absorption occur? - correct-answer -diffusion, facilitated diffusion,
osmosis, active transport
How does absorption work? - correct-answer -- food molecules are absorbed into
the blood or the lymph. To be absorbed in the body the molecules need to pass
into the capillaries or the villus. Fats absorb into the lymph
- Substances to be absorbed move from the lumen into the epithelial villi
- Amino acids and monosaccharides move from the villi into capillaries and
monoglycerides move into the lacteals
What are some of the digestive enzymes? - correct-answer --typsinogen and
chymotrypsin (breaks down proteins)
-amylase breaks down starches and sugars
-lipase breaks down fats
