ANATOMY

Detailed explanation-1: -The right and left coronary arteries supply blood to your heart. They’re the first branches off the aorta, which is the main artery in your body. These arteries and their branches supply all parts of the heart muscle with blood.

Detailed explanation-2: -The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries).

Detailed explanation-3: -Two main coronary arteries originate from the base of the aorta as it exits the left ventricle: the left and right coronary arteries. These arteries further branch into smaller arteries to supply specific parts of the heart like the atria, ventricles, SA, and AV nodes.

Detailed explanation-4: -The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. The coronary arteries wrap around the entire heart.

Detailed explanation-5: -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).
