Verified

In “crustaceans” there exist pair of excretory organs which are called as green glands. Green glands collect the residuals from blood to other parts of the body. They are attached by ducts to the excretory pores situated under the base of antennae and these pores liberate excretions outside. In insects’ small structures which are named as malpighian tubules collect wastes from blood and put them into the excretory ducts which open in intestine. Excretions are removed together with feces in these animals. In “arachnids”, other than malpighian tubules, Coxal glands are also there which is situated in the cephalothorax nearby the limbs which participate in the excretion.
