Explanation:
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: -In the small intestine, absorption occurs through the lumenal face of the mucosa, which is covered with finger-like projections called villi. Each villus is bordered by several pouches or invaginations called crypts. On the average, each villus is surrounded by eight crypts.
