Detailed explanation-1: -The organs and tissues are directly bathed in blood. As a result, there is no differentiation between blood and interstitial fluid. As a result, hemolymph is used. The heart pumps the hemolymph through the arteries into the sinuses, where it exchanges materials with the surrounding cells.
Detailed explanation-2: -In an open circulatory system, the blood is not enclosed in the blood vessels, but is pumped into a cavity called a hemocoel. The blood is called hemolymph because it mixes with the interstitial fluid.
