The earthworm’s digestive system is one of the most important system in the worm. There are no jaws and teeth, and the earthworm sucks in the soil containing food with the muscular pharynx. Earthworms feed upon all kinds of organic humus and debris such as decaying leaves and seeds, protozoan, etc.
A Flatworm Is Shown In Figure 1.
The digestion of a flatoworm begins with enzymes secreted onto the food before it becomes sucked into the intestine by the pharynx. They contract in a wavelike style, driving material down the length of the digestive system. The gizzard grinds the food.
For More Surface Area For Increased Absorption Of Nutrients, The Intestine Has Lateral Branches.
These flatworms feed through a pharynx. In numerous bigger flukes parallel intestinal branches or diverticula, bring food near every internal tissue. This suction motion aids in helping the worm consume large amounts of food in a short amount of time.
