EB069001	Protein, carbohydrate, and fat molecules from food are broken down in the digestive system into smaller molecules (subunits) that can enter the blood stream and be distributed throughout the body.
EB070001	Amino acids but not proteins pass from the digestive system to the circulatory system.
EB073001	After eating a meal that is high in protein, the level of amino acids in blood vessels flowing toward the small intestine is lower than in blood vessels flowing away from the small intestine.
EB074001	After eating a meal, the level of glucose is higher in blood flowing away from the small intestine than toward it, whereas after an overnight fast the level of glucose is low in both blood flowing toward and flowing away from the small intestine.
EB080001	In order of increasing size, the components of the circulatory system are carbon atom, amino acid, protein, red blood cell, blood vessel.
