What is a rear descending artery?

The rear descending artery, which is also known as the rear -intertricular artery, is the branch of one of the main arteries of the heart. In most people, the branch of the rear descending artery from the right coronary artery, which is called the true dominance of the coronary artery. In the left dominance of the coronary artery with the rear descending artery of the branch from the left peripheral artery. With coronary artery dominance with rear descending artery of branches of right coronary artery and left peripheral artery.

Human heart has four chambers. On the left side of the heart is the left hall at the top and the left chamber at the bottom. On the right side of the heart is the right atrium at the top and the right chamber at the bottom. The left side of the heart gets oxygenated blood from the lungs through the lung vein. Aorta, which is the largest and longest arteries, carries oxygenated blood from the left ventricle to the rest of the body. The right and left pulmonary arteries branch from the main pulmonary artery and transfer blood to the corresponding lungs. With the exception of corded arteries on fruits, the pulmonary artery is the only arteries in the body that bear deoxygenated blood.The main pulmonary artery is the only main artery that does not turn off from the aorta.

coronary arteries branch from the aorta and reach to the walls of the heart. They add blood to the hall, chambers and heart septum, a wall that divides the right and left sides of the heart. The real coronary artery adds blood rich in oxygen to the walls of both chambers and right atriums. The left coronary artery distributes blood to the light, the left front descending artery and the left peripheral artery.

The right branch of the coronary artery, called the rear descending artery, provides the lower wall of the left ventricle and the lower part of the oxygen -rich septum. The left front descending artery provides the back of the septum, the walls of the chambers and the front of the left atrium with oxygenated blood. The left peripheral artery provides the walls of the chamber and the rear of the left atrium with blood rich in oxygen.
