Most part of the two is similar in that the food goes in from the mouth and the waste products comes out of the anus. But the earthworms use small stones, which they consumed, in the gizzard to grind down food as oppose to human with a stomach. Human do not need to use little stones and food is both mechanically and chemically digested in the stomach.
