In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
The Earthworm eliminates by means of nephrdia.
An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.

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 kidney, which is part of the excretory system.
The function of these openings is to excrete waste from the earthworms body.
