Thorax and abdominal organs
The illustration shows a cranium opened up sagitally as well as a transparent torso with the organs it contains. The digestive tract is highlighted. The colon is the last part of the digestive system. It is composed of the appendix, caecum, colon (ascending, transversal, descending, and sigmoid colon) and rectum. The colon is where reabsorption of water happens, and the feces are stored until defecation.
