THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

Detailed explanation-2: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach.

Detailed explanation-3: -In fact, over 95 percent of the nutrients gained from a meal, including protein, fat, and carbohydrate, are absorbed in the small intestine. Alcohol, an additional source of energy, is largely absorbed in the small intestine, although some absorption takes place in the mouth and stomach as well.
