Ileum. The digestive system is the organ system that breaks food down into small molecules that are absorbed into the bloodstream. The residue then passes through the ceca, a blind sack along the lower intestinal tract, where bacteria help break down undigested food. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. This peristalsis and absorption continues through both the small (duodenum, Jejunum, Ileum) and large intestine (Caecum, Ascending, transfers, depending, sigmoid colon). 1. Figure 15.5.
