ANATOMY

Detailed explanation-1: -The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins. The lowest part of your small intestine is the ileum. This is where the final parts of digestive absorption take place. The ileum absorbs bile acids, fluid, and vitamin B-12.

Detailed explanation-2: -The inside of the small intestine is lined with villi that absorb nutrients from the liquid mixture called chyme produced in the stomach from the food we eat.

Detailed explanation-3: -Villi That Line the Walls of the Small Intestine Absorb Nutrients. Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels called lacteals.

Detailed explanation-4: -Examples of nutrients absorbed by the small intestine include carbohydrates, lipids, proteins, iron, vitamins, and water.

Detailed explanation-5: -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.
