Interconnected Systems
Immune System
Immune system protects digestive system from pathogens and foreign substances.
Intestinal epithelial cells secrete mucus and produce antimicrobial peptides, aiding immune defense.
Circulatory System
Circulatory system transports absorbed nutrients to various tissues and organs.
Nutrients absorbed into bloodstream through capillaries in small intestine villi.
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.
