The Intestines

p. 461-467, 474-478

small intestine anatomy
Small Intestine Anatomy
  • Pyloric sphincter
  • Duodenum
  • Jejunum
  • Ileum
  • Ileocecal valve
  • Coils attached to mesentery
small intestine functions
Small Intestine Functions
  • Completes chemical digestion
  • Absorbs nutrients & H2O
    • Huge surface area (villi & microvilli in jejunum & ileum)
sm intestinal secretions
Sm. Intestinal Secretions
  • Goblet cells– mucus
  • Intestinal glands – secrete “brush border enzymes” to digest:
    • Carbs  monosacch.
    • Proteins  AA’s
  • Duodenum also receives secretions of liver (via bile duct) & pancreas (via pancreatic ducts)
nutrient absorption
Nutrient Absorption
  • Huge surface area
    • Circular folds, villi, microvilli
  • Absorption  capillary beds, lacteals
  • Peyer’s patches – keep bacteria out of bloodstream
large intestine anatomy
Large Intestine Anatomy
  • Haustra
  • Ileocecal valve
  • Cecum
  • Appendix
  • Colon
    • Ascending
    • Transverse
    • Descending
    • Sigmoid
  • Rectum
  • Anal canal
large intestine functions
Large Intestine Functions
  • No digestive function
  • Goblet cells – mucus
  • Beneficial bacteria – make vitamins we can use (K, some B) and gas
  • Absorbs water, some vitamins, & electrolytes – but no villi
  • Elimination of feces
