ANSWER

NEHRIDA

Explanation

Earthworms (annelids) have slightly more evolved excretory structures called nephridia, illustrated in . A pair of nephridia is present on each segment of the earthworm. They are similar to flame cells in that they have a tubule with cilia. Worms have nephridia to filter out the dead cells and other wastes that are sloughed into the blood. Wastes from the nephridia are eliminated through the same opening as the digestive wastes. Worm urine is more dilute than ours, but has ammonia as well as urea.
