Single circulatory systems are less complex and sufficient for less active animals, but have slower blood flow, lower efficiency, and mixed oxygenated/deoxygenated blood. Double circulatory systems offer adjustable pressure, higher pressure, fast blood flow for efficient oxygen delivery, and no mixing of oxygenated and deoxygenated blood.
