yes this is answer.
An earthworm and all insects are invertebrates because they lack an internal skeleton, especially because they don't have a backbone.Well to tell you an earthworm is an invertebrate.An earthworm is an invertebrate.
Roundworms, such as Ascaris lumbricoides.See http://en.wikipedia.org/wiki/Ascarid
It can be positive or negative, but mostly negative because humans are the biggest predator of earthworms.
The actual "pumping system" of a worm can be mistaken as a heart, but it has no chambers. They are actually aeortic arches that pump the blood down the ventral side of the worm and it returns on the dorsal vessel.
Cellulose is digested by cellulase.It is not found in human.
The primary function of cilia is that of movement. They can be found on bacteria, microscopic organisms and even in the human digestive and reproductive systems.
Bacteria
In the human body "good" bacteria can be found in the stomach and digestive system.

There are many differences and similarities between a perch and a human in the digestive system. One is the enzymes found in the gut.
Cellulase, papain, amylase, and lipase are just a few of the ones that can be found in the digestive system. They all act on different substrates though.
A bolus is formed in the mouth and travels through the whole digestive system of a human.
Ventral is the lower part of the body(light-colored on a earthworm)(stomachs on a human) and dorsal is the top(butts on a human)(darker side on a earthworm)

Earthworm are like human cause they have a complete losed circulatory system. The earthworm has red blood that contains respiratory pigment similar to hemocfokin. External respiration in human must be moist and an earthworm keep its body surface.
