What is the mechanism that a nutrient gets transported from within a small
intestine to the lymph or bloodstream?  Are there pores of limited size?
Once the nutrient is in the lymph or bloodstream, how does a "hungry" cell
"grab" a desired nutrient?  What makes the immune system think a nutrient is
not an antigen?
