Open circulatory system

Explanation:

An open circulatory system, found in arthropods, pumps blood into a cavity called a hemocoel where it surrounds the organs and then returns to the heart(s) through ostia (openings). The blood found in arthropods, a mix of blood and interstitial fluid, is called hemolymph.Arthropods have an open circulatory system. In an open circulatory system, blood isn't transported in the body through veins and arteries; it flows freely within body cavities and makes direct contact with the organism's internal tissues and organs! Most arthropods that live in the water have gills.
