Digestive System: Which part of the digestive system absorbs most nutrients?

The small intestine, with its specialized lining of finger-like villi and microvilli, provides a vast absorptive surface. Nutrients including amino acids, monosaccharides, fatty acids, glycerol, vitamins, and minerals are absorbed into the blood and lymphatic capillaries (lacteals) in the intestinal wall during the small intestine’s jejunal and ileal phases.
