Open Circulatory System Closed Circulatory System 12.1 - 2 Types of CS
Open Circulatory System A CS in which vessels open into the animal’s body cavity and makes direct contact with organs and tissues Closed Circulatory System 12.1 - 2 Types of CS
Open Circulatory System A CS in which vessels open into the animal’s body cavity and makes direct contact with organs and tissues. There is no distinction between the blood and the interstitial fluid (a solution surrounding cells of multicellular animals). The mixture of blood and the surrounding fluids is called hemolymph. Closed Circulatory System A CS in which the circulating blood is contained within vessels and kept separate from the interstitial fluid. 12.1 - Open & Closed CS
