Question

discuss the location of nephridia in earthworm

Answer 1

Nephridia, coiled tubular duct-like organs, filter and remove waste from an earthworm's body. In less developed worms such as the flatworm or the rotifer, the nephridia are not as specialized and are located in various cells throughout the creature's body. In more advanced segmented worms, like the earthworm, the nephridia typically are grouped in pairs throughout the segments of the worm's body. These pairs of nephridia are named for their location in the worms anatomy. Each group shares similarities, they are all waste conduits, but each also has distinctive functions.
