ANATOMY

Detailed explanation-1: -The majority of chemical digestion occurs in the small intestine. Digested chyme from the stomach passes through the pylorus and into the duodenum. Here, chyme will mix with secretions from both the pancreas and the duodenum.

Detailed explanation-2: -The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy. There are lots of enzymes released in the small intestine and from the nearby pancreas for digestion.

Detailed explanation-3: -Where Does Chemical Digestion Occur? Chemical digestion takes place throughout your digestive tract. Chemical digestion begins in your mouth with your saliva. The process continues in your stomach and is completed in your small intestine.

Detailed explanation-4: -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-5: -Although the glands of the large intestine secrete mucus, they do not secrete digestive enzymes. Therefore, chemical digestion in the large intestine occurs exclusively because of bacteria in the lumen of the colon.
