These different sections are separated by bands of muscles, or sphincters, which act as valves. The passage of food from one area of the intestines to another is coordinated so that food stays in a specific area for long enough for the gut to do a particular job — absorb fluids and nutrients, or process and expel waste.
Food passes from the stomach into the duodenum, which is the tube that leads from the stomach into the intestines.
The food then passes through the jejunum and ileum before going to the large bowel colon. The small bowel small intestine absorbs nutrients and much of the liquid from foods. The large bowel also known as the colon, or large intestine , starts at the final portion of the small bowel small intestine and goes all the way to the rectum. The large bowel colon is about 2m long and cm wide. This muscular tube is made up of the ascending colon, the transverse colon and the descending colon which ends at the rectum and the anus.
The colon also absorbs some nutrients and water. Waste is expelled through the anus. Once the bowel has done its work and absorbed nutrients from food, the waste travels to the rectum which stretches, triggering a message to the brain to say that the bowel is full and needs to be emptied. After food has travelled along the gut, it has become digested and the nutrients and fluids absorbed; the waste is then expelled through the rectum and anus.
The rectum and the upper portion of the anal canal are richly supplied with nerves.
