d)Respiratory system : tracheal in insects, branchial in crustaceans, tracheal and book lungs in arachnids.
e) Circulatory system : open, hemocyanin in crustaceans and arachnids.
f) Excretory system : malpighian tubules in insects, malpighian tubules green glands in crustaceans, and coxal glands in arachnids.
g) Nervous system : ganglial.
