All these enzymes like proteases, amylases and lipases act upon the finely ground food and digest the organic matter in it.
Segmentation can help the earthworm move.
Also there occurs the complete digestion of protein by proteolytic enzymes. It has a beaded appearance due to constrictions corresponding to septa but bulging in each segment. Receptor cells are sensory in function.
The intestinal juice of the earthworm is comparable to the pancreatic juice of higher animals. The bristles or setae help anchor and control the worm when moving through soil. The intestines absorb most of the digested food required by the earthworm and pass out the indigested food outside of the body through the anus.
The earthworm’s digestive system is one of the most important system in the worm. Now the food material enters into intestine.
The prostomium or mouth of an earthworm is made up of strong lips. In intestine, intestinal caeca produce amylase which converts starch into glucose. In intestine several enzymes are secreted and acts on the substrate as follows: Protease: converts protein into amino acid. Post navigation.
The buccal cavity is made up of 2½ segments that is thin-walled and shaped like a pear.

Comment. Intestine: The stomach is extending from 15th segment up to the anus.

The earthworm is made of about 100-150 segments. The presence of typhlosole in the greater a part of the intestine increases the surface both for digestion and absorption.
