ANATOMY

Detailed explanation-1: -Digestion and absorption of all biomolecules are completed in the intestine. The small intestine has 3 parts namely-the duodenum (c-shaped), jejunum, and ileum. Complete digestion of food takes place in the ileum.

Detailed explanation-2: -Digestion involves mixing food with digestive juices, moving it through the digestive tract, and breaking down large molecules of food into smaller molecules. Digestion begins in the mouth, when you chew and swallow, and is completed in the small intestine.

Detailed explanation-3: -Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.

Detailed explanation-4: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.
