The time for one complete heartbeat, from the beginning of one systole to the beginning of the next. Provide the students with a diagram of the major blood vessels for labeling.
When blood reaches the veins, the pressure is very low, and so instead of veins having a pulsatile ability to maintain pressure, they instead have valves to prevent backflow. The right side of the heart is still sending blood to the lungs, but the left side of the heart, the systemic pump, is not pumping blood entering its chamber from the pulmonary circuit to the systemic circulation.The Cardiovascular system is actually two different systems, the cardio system which refers to the heart and the vascular system which refers to the blood.
