Question:medium

The percentage of body's blood volume that veins hold is:

Show Hint

Think of your cardiovascular system as having two distinct halves: - Arteries = Pressure Reservoirs: They carry small volumes of blood under high pressure to drive perfusion. - Veins = Volume Reservoirs (Capacitance Vessels): They hold roughly $60%$ of your total blood supply under low pressure, acting as a buffer that the body can tap into during exercise or blood loss.
