After leaving your lungs, your blood enters your left atrium and from there flows into your left ventricle. Your left ventricle then pumps this blood out to your body, where it makes the rounds before returning to your heart.
The left atrium receives to high-oxygen blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the high-oxygen blood to the rest of the body.
The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.
The left ventricle generates the high pressure needed to pump the blood to your whole body through your blood vessels. When blood leaves the heart to go to the rest of the body, it travels through a large artery called the aorta.
The left ventricle is an integral part of the cardiovascular system. Left ventricular contraction forces oxygenated blood through the aortic valve to be distributed to the entire body. With such an important role, decreased function caused by injury or maladaptive change can induce symptoms of the disease.
The right side of the heart collects oxygen-depleted blood from the body and brings it to the lungs to be filled with fresh oxygen. The left side of the heart receives oxygen-rich blood from the lungs and sends it out to the rest of the body.
The right side of the heart receives blood that is low in oxygen because most has been used up by the brain and body. It pumps this to your lungs, where it picks up a fresh supply of oxygen. The blood then returns to the left side of the heart, ready to be pumped back out to the brain and the rest of your body.
The left and right atria are smaller chambers that pump blood into the ventricles. The left and right ventricles are stronger pumps. The left ventricle is the strongest because it has to pump blood out to the entire body.
The left atrium receives blood from the lungs. This blood is rich in oxygen. The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
The structure of the heart
On the right side of the heart, the right atrium and right ventricle work to pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated. On the left side of the heart, the left atrium and left ventricle combine to pump oxygenated blood back through the body.
The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
The aorta is the largest artery of the body and carries blood from the heart to the circulatory system.
Your carotid arteries are blood vessels that supply blood to your brain, face and neck. You have two common carotid arteries, one on each side of your neck: Left common carotid artery. Right common carotid artery.
The femoral artery is the major blood vessel supplying blood to your legs. It's in your upper thigh, right near your groin.
The blood gives up oxygen and nutrients to the muscles and tissues in the legs and then returns to the heart through the veins. The heart can pump blood to the legs and so, unless the arteries are blocked, the blood gets to the feet fairly easily through the arteries.
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood picks up oxygen and gets rid of carbon dioxide.
left atrium: The left atrium is one of the four chambers of the heart. It receives oxygen-rich blood from the lungs and then empties the blood into the left ventricle through the mitral valve.
Left-sided heart failure is the most common type. Right-sided heart failure: Here the right ventricle of the heart is too weak to pump enough blood to the lungs. This causes blood to build up in the veins (the blood vessels that carry blood from the organs and tissue back to the heart).
Generally, heart failure starts on the left side – specifically, the left ventricle, your heart's main pumping chamber. Heart failure often occurs after another condition has weakend the heart. Any of the below conditions can weaken the heart and cause heart failure: Coronary artery disease and heart attack.
The right side of the heart usually becomes weaker in response to failure on the left side. The right side of the heart brings in the circulated blood from the body and sends it to the lungs for oxygen. When the left side of the heart weakens, the right side of the heart has to work harder to compensate.
If you have right ventricular failure, this means that the muscle of your right ventricle is not pumping as efficiently as it should be. This can be caused by a number of conditions, including leftsided heart failure, high blood pressure in the lungs and heart valve disease.
The damaged right side stops pumping efficiently, and blood builds up in the veins. As pressure increases in the veins, it pushes fluid into surrounding tissues. The fluid buildup causes swelling and congestion throughout your body.
Cor pulmonale is a condition that causes the right side of the heart to fail. Long-term high blood pressure in the arteries of the lung and right ventricle of the heart can lead to cor pulmonale.
The left ventricle is the strongest and most important chamber of your heart. The walls are only 1/2 inch thick but they are strong enough to pump blood to your whole body.
