uptake of nutrient molecules into the epithelial cells of the digestive tract and then into the blood and lymph
,Compaction
absorbing water and consolidating the indigestible residue into feces
Defecation
elimination of feces
Peritoneum
the largest serous membrane in the body
1. lines the abdominal cavity
