Earthworms have blood and it is enclosed in a network of tubes much like the blood system of mammals. It is red because it contains the oxygen carrying pigment hemoglobin. Unlike mammals, where the hemoglobin is inside red blood cells, earthworm hemoglobin is just mixed in the liquid of the blood, commonly called hemolymph.
Earthworms pump their blood around the body with the help of 5 specialized blood vessels that contract and expand. They are the worm's hearts.
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.
the brain is essential for the movement of the earthworm. If the brain of the earthworm is removed, the earthworm will move continuously without stop
Pair of nephridia in earthworm's segments excretes waste through pores in the skin, removing waste from the blood and body fluids.
Yes, an earthworm is a decomposer.
The earthorm has a closed circulatory system with five main blood vessels:Dorsal (above the digestive tract) - it moves blood forwardThe remaining four all move the blood to the rear of the earthworm: Ventral (beneath the digestive tract)Subneural Vessel (below the nerve cord)Right & Left Lateroneural vessels (either side of nerve cord)

This artery is called the dorsal aorta and it is a main artery leading from the heart. It divides and branches out to smaller arteries that ensure that all of the body is supplied with oxygen.
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.
