Small intestine

The primary function of the small intestine is the absorption of nutrients from digested food, facilitated by its intricate structure comprising the duodenum, jejunum, and ileum. The presence of villi and microvilli significantly increases the surface area for more efficient nutrient absorption.

Main Function

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
Intestinal epithelial cells secrete mucus and produce antimicrobial peptides, aiding immune defense.
Immune system protects digestive system from pathogens and foreign substances.
