The reason why most absorption of nutrients and water happen in the intestines, is because the colon accepts what the small intestine doesn't absorb. The intestines include the small intestine, large intestine, and rectum (4). The rectum is the concluding part of the large intestine that terminates in the anus. This is where the water from the chyme, the stomach’s gastric juices which breaks down proteins and kills harmful bacteria, is absorbed back into the body (8). The key role of the rectum is to acts as a temporary storehouse for feces until they are eliminated from the body through defecation
