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.Click to see full answer. Moreover, do Arthropods have an open or closed circulatory system?Arthropods have what is referred to as an open circulatory system, where blood fills the body cavity of the animal. Humans have a closed circulatory system, where blood is moved around the body via vessels and arteries. This cavity is referred to as a haemocoel, or blood cavity. why do Arthropods have open circulatory system? Arthopods and Mollusca have open circulatory system because as they have air sacs to supply blood to the heart so oxygen has also supply to all over body. Their circulatory system helps to supply oxygen to entire body and disposes carbon dioxide. In this way, what is an open circulatory system? Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.Does an earthworm have an open or closed circulatory system?Most vertebrates and some invertebrates, like this annelid earthworm, have a closed circulatory system. In (b) open circulatory systems, a fluid called hemolymph is pumped through a blood vessel that empties into the body cavity. Hemolymph returns to the blood vessel through openings called ostia.
