pump blood around the body
example of double circulatory system
blood passes through the heart and is pumped to the lungs, returning back to the heart (pulmonary circulation). blood passes through the heart a second time (the blood is re-pressurised) and pumped around the body organs before returning to the heart (systemic circulation)
example of mass flow
blood moves around the body due to pressure differences between the pressure in the heart (high) and the pressure in the blood vessels (low)
