Final answer:

Nephridia in earthworms act as excretory structures filtering fluid and carrying out waste removal through nephridiopores.


Explanation:

Structure of Septal Nephridia of Earthworm

Nephridia are excretory structures in earthworms, each segment housing a pair. They function akin to kidneys, filtering fluid from the coelom through ciliated tubules. This fluid passes down the tubules, undergoing reabsorption of nutrients, and wastes are eventually secreted through the nephridiopore.
