THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Digestion ends in the small intestine of the human body. The digestive process starts in the mouth and finishes in the small intestine. The small intestine, which has three parts called the duodenum, jejunum, and ileum, uses bile from the liver and enzymes secreted by the pancreas to break down 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: -The digestive tract begins at the mouth and ends at the anus.

Detailed explanation-4: -Duodenum. To help break food down, the small intestine receives digestive juices from other organs in your digestive system, including your liver, gallbladder and pancreas. Ducts from these organs feed into the duodenum.
