LARGE INTESTINE

Dr Iram Tassaduq

large intestine1
LARGE INTESTINE
  • The primary function of the large intestine is the reabsorption of water and inorganic salts. The only secretion of any importance is mucus, which acts as a lubricant during the transport of the intestinal contents.
  • Movements sluggish (18-24 hours)
large intestine2
LARGE INTESTINE

Has three unique features:

  • Teniae coli – three bands of longitudinal

Smooth muscle in its muscularis

  • Haustration – pocket like sacs caused by the tone of the teniae coli
  • Epiploic appendages – fat-filled pouches of visceral peritoneum
mucosa
MUCOSA
  • The surface of the mucosa is relatively smooth as there are no plicaecirculares or intestinal villi. Crypts of Lieberkühn are present and usually longer and straighter than those of the small intestine. Goblet cells account for more of the epithelial cells than in the small intestine
lamina propria
LAMINA PROPRIA
  • There is only little lamina propria squeezed between the glands
muscularis externa1
MUSCULARIS EXTERNA
  • The inner circular layer of muscle forms the usual sheath around the large intestine, but the outer longitudinal muscle layer forms three flattened strands, the taenia coli. Only a thin layer of longitudinal muscle surrounds the inner circular muscle layer between the taenia coli
