Absorption of nutrients from digested food.
Consists of three segments: duodenum, jejunum, and ileum.
Villi and microvilli increase surface area for absorption.
Enterocytes absorb nutrients into bloodstream.
Absorbed nutrients include sugars, amino acids, fatty acids, vitamins, and minerals.
Water absorption also occurs in the small intestine.
Interconnected Systems
Circulatory System
Nutrients absorbed into bloodstream through capillaries in small intestine villi.
Circulatory system transports absorbed nutrients to various tissues and organs.
Immune System

Immune system protects digestive system from pathogens and foreign substances.
