Question

Quizplus · Accepted Answer

The excretory organs in insects are Malpighian tubules, which are responsible for creating an excretory fluid by secreting K+, Na+, Cl-, and HCO3- ions. These ions draw water osmotically, and the resulting fluid is excreted into the hindgut for elimination. Flame cells are excretory cells found in flatworms, while kidneys, glomeruli, and loops of Henle are found in vertebrates and are not present in insects.
