Histology of Large Intestine -

  • The wall of the large intestine has a few enzyme-secreting cells.
  • There are no circular folds or villi.
  • Other than in the anal canal, the mucosa of the colon is simple columnar epithelium made mostly of enterocytes (absorptive cells) and goblet cells.
  • The wall of the large intestine has far more intestinal glands.
  • These goblet cells secrete mucus that eases the movement of faeces and protects the intestine from the effects of the acids and gases produced by enteric bacteria. 
  • The enterocytes absorb water and salts as well as vitamins produced by intestinal bacteria.
