Right coronary artery (RCA): Supplies blood to the right atrium, right ventricle, bottom portion of the left ventricle and back of the septum.Left anterior descending artery (LAD): Supplies blood to the front and bottom of the left ventricle and the front of the septum.Circumflex artery: Supplies blood to the left atrium and the side and back of the left ventricle.Left coronary artery: Divides into two branches (the circumflex artery and the left anterior descending artery).These arteries run along your heart’s surface. Your heart receives nutrients through a network of coronary arteries. Capillaries are small blood vessels where your body exchanges oxygen-rich and oxygen-poor blood.Veins carry oxygen-poor blood back to your heart.The exception is your pulmonary arteries, which go to your lungs. Arteries carry oxygen-rich blood from your heart to your body’s tissues.Your heart pumps blood through three types of blood vessels: Pulmonary valve : Opens when blood flows from your right ventricle to your pulmonary arteries (the only arteries that carry oxygen-poor blood to your lungs).Aortic valve: Opens when blood flows out of your left ventricle to your aorta (artery that carries oxygen-rich blood to your body).Semilunar (SL) valves open when blood flows out of your ventricles. Mitral valve: Door between your left atrium and left ventricle.Tricuspid valve: Door between your right atrium and right ventricle.The atrioventricular (AV) valves open between your upper and lower heart chambers. They open and close to allow blood to flow through. Your heart valves are like doors between your heart chambers. It pumps oxygen-rich blood to the rest of your body. Left ventricle: The left ventricle is slightly larger than the right.This upper chamber pumps the blood to your left ventricle.

Left atrium: After the lungs fill blood with oxygen, the pulmonary veins carry the blood to the left atrium.

Right ventricle: The lower right chamber pumps the oxygen-poor blood to your lungs through the pulmonary artery.

Then the right atrium pumps the blood to your right ventricle. The inferior vena cava brings blood from the lower body. The superior vena cava carries blood from your upper body.

Right atrium: Two large veins deliver oxygen-poor blood to your right atrium.

You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of the heart. Your heart is divided into four chambers. It produces fluid to lubricate your heart and keep it from rubbing against other organs. The pericardium is a protective sac that covers your entire heart. The epicardium is one layer of your pericardium. A layer of muscular tissue called the septum divides your heart walls into the left and right sides. Your heart walls are the muscles that contract (squeeze) and relax to send blood throughout your body.

Electrical conduction system (electricity).

The parts of your heart are like the parts of a house. What are the parts of the heart’s anatomy? Your heart may weigh a little more or a little less, depending on your body size and sex.
