The coronary arteries supply blood to cardiac tissue. Which chamber of the heart requires the greatest amount of blood supply to
kondor19780726 [428]

The coronary arteries supply blood to cardiac tissue. The left ventricle chamber of the heart requires the greatest amount of blood supply to keep it working.

Coronary arteries

The heart muscle receives blood from the coronary arteries. The heart muscle needs oxygen-rich blood in order to operate, just like all other bodily components do. Blood that lacks oxygen must also be transported away. Outside of the heart, the coronary arteries encircle the organ.

The coronary artery that is blocked the most frequently is the LAD artery. The interventricular septum, and therefore bundle branches of the conducting system, receive their primary blood supply from it.
