GENERAL HISTOLOGY

Detailed explanation-1: -Mucosa. The walls of the small intestine are lined with a dense mucosa with many glands that both secrete and absorb. In the jejunum and the ileum, the mucosa secretes small amounts of digestive enzymes and lubricating mucus while absorbing nutrients from your food.

Detailed explanation-2: -Intestinal glands are found in the epithelia of the small intestine, namely the duodenum, jejunum, and ileum, and in the large intestine (colon), where they are sometimes called colonic crypts.

Detailed explanation-3: -Hence, succus entericus is the intestinal juice secreted by ileum.

Detailed explanation-4: -Enzymes secreted by intestinal glands are lipase, amylase, sucrase, lactase, maltase, aminopeptidase, carboxypeptidase, etc.

Detailed explanation-5: -PANCREAS. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. The pancreas delivers digestive juice to the small intestine through small tubes called ducts.
