Blood carries essential oxygen to the tissues and carries away unwanted carbon dioxide and other waste products. The blood circulates around the body through a system Aortic arch of blood vessels. The heart has four chambers - two on the left side and two on the Superior vena cava right. The two upper chambers are called the atria, and the two lower chambers are called the ventricles. The two sides of the heart are divided by a muscular wall called the septum. Each side of the Ascending aorta Left pulmonary artery heart has a ‘one-way valve system’, which means that the blood travels only in one direction through the heart. Know Left main coronary artery The right side of the heart receives de-oxygenated blood from the body. The blood is pumped through the pulmonary artery to the Circumflex artery Pulmonary trunk lungs where it picks up a fresh supply of oxygen. The left side of the heart receives oxygenated blood from the lungs Left atrium and pumps this through the aorta into the arteries which supply the rest of the body. your Left anterior descending Right coronary artery coronary artery Like every other living tissue the heart muscle (myocardium) needs to be continuously supplied with oxygenated blood. This supply of blood comes from the coronary arteries which start from the beginning of the aorta.
