Which organisms use Malpighian tubules to excrete uric acid?

Question

Quizplus · Accepted Answer

Insects have a unique excretory system consisting of long, thin tubules called Malpighian tubules attached to the gut. Uric acid, their primary nitrogenous waste product, simply diffuses from the surrounding hemolymph into these tubules, and water follows a salt gradient established by active transport of potassium K+). Water and other useful substances are reabsorbed at the rectum, but the uric acid leaves the body at the anus.
