Detailed explanation-1: -Your stomach, which is attached to the end of the esophagus, is a stretchy sack shaped like the letter J. It has three important jobs: to store the food you’ve eaten. to break down the food into a liquidy mixture.

Detailed explanation-2: -After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.

Detailed explanation-3: -Ileum. The ileum is the last and longest section of the small intestine. Here the walls of the small intestine begin to thin and narrow, and blood supply is reduced. Food spends the most time in the ileum, where the most water and nutrients are absorbed.

Detailed explanation-4: -In your stomach, the food mixes with those digestive juices, creating a watery concoction that passes into the small bowel. “The small bowel’s walls absorb needed nutrients and water, ” says Dr. Lee. “The colon (large bowel) then takes what your body didn’t use and prepares to get rid of it through a bowel movement.”
