GROSS ANATOMY

Detailed explanation-1: -The coronary arteries provide the main blood supply to the heart. The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body.

Detailed explanation-2: -Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function.

Detailed explanation-3: -Oxygenated blood is pumped into the aorta from the left ventricle. This is where it enters the right and left main coronary arteries, and subsequent branching feeds the myocardial tissue of all four chambers of the heart (see Figure 7).

Detailed explanation-4: -Your coronary arteries are around and inside your heart muscle. They branch off your aorta, which is the main artery in your body. They start at the aortic root, which is the first part of your aorta that emerges from the left ventricle of your heart.
