In earthworm the organs of excretion are the nephridia. Each nephridium is a long tube which opens at one end in to the body cavity by a ciliated funnel, the nephrostome and at the other end to the outside body by an opening, the nephridiophore in the skin. the nephrostome of a nephridium in a segment lies in the segment next in front of it. The nitrogenous wastes, such as ammonia and urea are collected by nephrostome, dropped into the lumen of the nephridium which contracts rhythmically pushing the waste products outside the body for removal through the nephridiophore in the skin.
They remove metabolic wastes from an animal's body.
The nephridia are tubelike structures that filter wastes from the blood
The function is to excrete waste.
The nephridia serves as a kidney :)
keeps it alive
To remove waste products.
Earthworms do not see. They function by means of the sense of touch.
earthworms travel faster
The annelids are segmented worms. Although some annelids have appendages and primitive sight organs (photo-reactive pigment spots), earthworms do not. Earthworms do, however, have the typical annelid neural ganglia, and the annelid circulatory system, including the aortic arches that function as the worm's heart. And, of course, earthworms are segmented.
Excretory organ found in earthworms and other animals.
It produced eggs .
keeps it alive
Pretty much the same as the function of a mouth in your body.
The function of an earthworm's gizzard is that the gizzard grinds organic matter.
The metanephridium is a type of excretory organ found in worms. It acts as a filtration system to remove metabolic waste and excess fluids from the body. The metanephridium helps to maintain the internal environment of the worm by regulating the concentration of solutes and fluids within its body.
The nephrids.
To remove waste products.
to quickly digest food and absorb nutrients
The function of an earthworm's aortic arches are to pump blood to the ventral blood vessel and into the body.
To carry the blood to all parts of the earthworm.
