THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Duodenum: This short section is the part of the small intestine that takes in semi-digested food from your stomach through the pylorus, and continues the digestion process. The duodenum also uses bile from your gallbladder, liver, and pancreas to help digest food.

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. It takes about 36 hours for food to move through the entire colon.

Detailed explanation-3: -After a meal, it normally takes 1 1/2 to two hours for food to move out of the stomach and into the small intestine.
