Insects have a heart of sort, in that it is a vessel that makes sure the haemolymph (insect blood) is constantly flowing throughout the body. The blood does not carry oxygen like ours does, as oxygen is delivered directly to their muscle tissue via their breathing system. They breathe through small tracheae throughout the body. Most segments in their body (save the head) have what are called spiracles on both sides. When the spiracle opens, air flows in, through the tracheae, branches off into trachioles (like branches off the tracheae, and then directly to the muscle tissue. Insects do have muscle tissue, although it is a different type than ours. In fact, most insects have more muscles in their body than we do, about 600 and change for us and up to well over a thousand fo
