Insects do not have veins in the same way that vertebrates do. Instead, they possess a system of tubes called tracheae that deliver oxygen directly to their tissues. Their circulatory system is open, meaning that hemolymph (the insect equivalent of blood) flows freely within the body cavity rather than being confined to vessels. Thus, while insects have a circulatory fluid, it does not involve veins as found in mammals.
