In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.

An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.
An annelid excretes solid waste through its anus. However, metabolic wastes are excreted by its nephridia, a pair of organs.
There are several other names used when referring to nephridia. Some of these include metanephridium, protonephridia, and metanephridia. It is basically an invertebrate organ that performs similar functions as the kidney.
