Question

Which of these are the excretory organs in earthworms?

• A. Nephridia
• B. Malphigian tubules
• C. Antennal glands
• D. Kidneys

Answer 1

The correct option is A

Nephridia

Nephridia are the tubular excretory structures seen in organisms like earthworms. They collect excretory products from the body cavity and eliminate through pores on the body surface. Malpighian tubules are the excretory structures of most of the insects including cockroaches. Malpighian tubules help in the removal of nitrogenous wastes and osmoregulation. Antennal glands perform the excretory function in prawns. Vertebrates have complex tubular organs called kidneys for excretion.
