The Department of Entomology has an "open" circulating system called the Grasshopper.
The open circulatory system of the cocks is different from that of other animals.The components of the circulatory system are the blood vessels.
What type of circulatory system do insects have?Like all arthropods, insects have an open circulatory system.Hemolymph is the insect blood that flows freely throughout the body.The insects have a vessel on their side that moves this hemolymph.
In insects, "blood" is confined to vessels during only a portion of its circuit through the body."blood" is called hemolymph for this reason.The volume of hemolymph needed for such a system is kept to a minimum.
The chambers in the hemolymph's circulatory system are similar to the human heart.The mid gut and hind gut are the same as the other organs in the insect and human.Food can also be aborted through an anus.
