Detailed explanation-1: -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.
Detailed explanation-2: -Open circulatory systems are systems where blood, rather than being sealed tight in arteries and veins, suffuses the body and may be directly open to the environment at places such as the digestive tract. Open circulatory systems use hemolymph instead of blood.
Detailed explanation-3: -Hemolymph serves as a water storage pool for use by tissues during desiccation and as a storage depot for other types of chemicals. It also contains circulating cells called hemocytes.
