They remove metabolic wastes from an animal's body.
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.

lungs skin and kidney
waste created by cellular metabolism is eliminated by the nephridia.
Pair of nephridia in earthworm's segments excretes waste through pores in the skin, removing waste from the blood and body fluids.
The function of an earthworm's nephridium is to excrete wastes from the earthworm's body.
if you mean nephridia (an extra 'i' second to end) they are specialised organs that function similar to kidneys in that they are used for osmoregulation and excretion. In annelids (which are segmented worms) there is one pair of nephridia per segment.
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
The water and nutrients are reabsorbed from the nephridia into the blood vessels surrounding the nephridia. This process helps to conserve essential substances and maintain the balance of fluids and solutes in the body.
nephridia
An annelid excretes solid waste through its anus. However, metabolic wastes are excreted by its nephridia, a pair of organs.
NEPHRIDIA:- In earthworm excretion occurs through nephridium. The excretory system in earth worm is closely associated with its closed circulatory system. Each segment of earthworm consists of a pair of nephridia or in some species cluster of nephridium. NEPHRoSTOME:- The colemic fluid or body fluid enters the nepridium through a membrane which is cilliated called nephrdiostome. NEPHRIDIOPORE:- The body fluid after reabsorption from the nephridia opens into a large bladder which opens to exterior through nephridiopore. Ammonia and water are waste products excreted by nephridia while CO2 is excreted through general body surface.
The phylum Annelida includes worms that excrete waste through structures called nephridia. Nephridia are tubular structures that filter waste from the coelomic fluid and release it outside the body through pores called nephridiopores.
