Briefly explain the role of Malpighian tubules in arthropods. What will be an ideal response?
Malpighian tubules absorb uric acid, salts, water, and wastes from the hemolymph. Some materials are
selectively reabsorbed into the hemolymph, and the rest is emptied into the gut. Uric acid is excreted
as a paste, and thus minimal water is lost. This efficient conservation of body fluids has contributed to
the success of insects.
