ANATOMY

Detailed explanation-1: -The small intestine extends from the pyloric sphincter to the ileocecal valve, where it empties into the large intestine. The small intestine finishes the process of digestion, absorbs the nutrients, and passes the residue on to the large intestine.

Detailed explanation-2: -Food is broken down by the digestive system to give energy to every cell in the body. The digestive tract starts at the mouth and ends at the anus.

Detailed explanation-3: -The small intestine is actually the longest segment of the gastrointestinal tract-the long, continuous pathway that food travels through your digestive system. In the small intestine, food is broken down into liquid and most of its nutrients are absorbed. The waste is passed on to the large intestine.
