When the blood circulates within our system‚ chemicals are exchanged by diffusion. Our cardiovascular system is made up of our heart‚ arteries and our veins. There is an important difference between the veins and the arteries. That difference is the flow or direction of the blood. Veins carry blood to the heart and arteries carry blood away from

P5 – Describe the Structure and Function of the Cardiovascular System Changes in Stroke Volume Stroke volume is the amount of blood pumped out the left ventricle‚ every beat your heart makes. It can differ from your resting heart beat and your heart beat when exercising. Normally‚ when exercising‚ your heart rate increases meaning the stroke volume also increases. The blood pumped by the left ventricle is oxygenated‚ and will deliver oxygen to the muscle. The more blood injected in a heartbeat means
