 Alimentary Canal of Earthworm

  • The alimentary canal is a straight tube that runs between the first segment to the last segment of the body of an earthworm.
  • At segment 26, a pair of intestinal caeca project from the intestine.
  • From segments 26 to 35, the intestine shows a characteristic feature called typhlosole.
  • Typhlosole is the internal medial folds of the dorsal wall. 
  • Typhlosole increases the effective area of absorption in the intestine.
  • The alimentary canal opens into the anus which is a round small aperture.
  • During digestion, the ingested soil is passed through the digestive tract and is digested into small absorbable substances which are absorbed through the membranes of the intestine.
