GENERAL HISTOLOGY

Detailed explanation-1: -Lipids, proteins, and complex carbohydrates are broken down into small and absorbable units (digested), principally in the small intestine. The products of digestion, including vitamins, minerals, and water, which cross the mucosa and enter the lymph or the blood (Absorption).

Detailed explanation-2: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins.

Detailed explanation-3: -Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-4: -The body absorbs monosaccharides (the break down product of carbohydrates) in the small intestine. Monosaccharides are absorbed across the intestinal epithelium to be transported through the bloodstream and used by different cells in the body.

Detailed explanation-5: -Absorption is the passage of nutrients through the intestinal walls and into the blood. The primary site of absorption is the small intestine. The villi, which are tiny finger-like projections, trap the nutrients which are taken in by the adjacent cells.
