De-oxygenated blood enters the right side of the heart and is pumped towards the lungs to pick up oxygen. Then that oxygen-rich blood re-enters the heart on the left side and is pumped out to the cells of the body.

Physical exertion will force your heart to beat faster and raise your heart rate. Many factors can also affect your resting heart rate. These include:. Exercise strengthens your heart muscle so it works more efficiently and supports blood flow. Exercise also helps you maintain a healthy weight, reduces your risk of high cholesterol and high blood sugar, and improves blood vessel function, all of which will also help blood circulate effectively. Did you know the most common forms of heart disease are largely preventable?

Our guide will show you what puts you at risk, and how to take control of your heart health. National Heart, Lung, and Blood Institute. Conduction disorders.

At each body part, a network of tiny blood vessels called capillaries connects the very small artery branches to very small veins.

The capillaries have very thin walls, and through them, nutrients and oxygen are delivered to the cells. Waste products are brought into the capillaries. Capillaries then lead into small veins. Small veins lead to larger and larger veins as the blood approaches the heart. Valves in the veins keep blood flowing in the correct direction.

Two large veins that lead into the heart are the superior vena cava and inferior vena cava. The terms superior and inferior don't mean that one vein is better than the other, but that they're located above and below the heart. Once the blood is back in the heart, it needs to re-enter the pulmonary circulation and go back to the lungs to drop off the carbon dioxide and pick up more oxygen.

How Does the Heart Beat? This is when the ventricles contract and pump blood into the aorta and pulmonary artery. During systole, the atrioventricular valves close, creating the first sound the lub of a heartbeat. When the atrioventricular valves close, it keeps the blood from going back up into the atria. During this time, the aortic and pulmonary valves are open to allow blood into the aorta and pulmonary artery. When the ventricles finish contracting, the aortic and pulmonary valves close to prevent blood from flowing back into the ventricles.

These valves closing is what creates the second sound the dub of a heartbeat. The second phase is called diastole die-AS-tuh-lee. This is when the atrioventricular valves open and the ventricles relax. Medical Review: Rakesh K. This information does not replace the advice of a doctor.

Topic Overview The heart is at the centre of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body.

How does my heart pump blood? The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body. How does blood flow through the heart?
