Discuss about Malpighian tubules

Malpighian tubules are the primary excretory and osmoregulatory organs found in insects, myriapods, and arachnids. They are slender, blind-ended tubes that extend from the alimentary canal and float freely in the hemolymph (insect blood). Their main function is to absorb solutes, water, and wastes from the hemolymph and empty them into the hindgut for excretion.
