• Intestine is divisible into 3 regions – Pre – typhlosolar, typhlosolar and post – typhlosolar region.

• Typhlosolar region has median dorsal internal fold.

• Body wall is composed of thin cuticle, columnar epidermis, thin circular muscle layer and thick longitudinal muscle layer.

• Typhlosole increases the surface area for absorption.

• Dorsal blood vessel, supra – intestinal excretory duct ventral blood vessel, nerve cord, sub – neural vessel, blood capillaries and coelom are seen in section.

• Section is triploblastic with organ grade of construction and true coelom.

• Typhlosole has chlorogen cells and a capillary blood vessel.

• Intestine is composed of outer visceral coelomic epithelial layer, intermediate longitudinal and circular muscle layers.
