MICROANATOMY

Detailed explanation-1: -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. It takes about 36 hours for food to move through the entire colon.

Detailed explanation-2: -Peristalsis moves food through the digestive tract with alternating waves of muscle contraction and relaxation.

Detailed explanation-3: -The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Detailed explanation-4: -The small intestine is involved in the digestion of food and absorption of nutrients. The large intestine is involved in the absorption of water and in the production of vitamins.
