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 first branch of the aorta is normally the innominate artery, which is also referred to as the brachiocephalic trunk. Shortly after its origin, the innominate artery divides into the right subclavian and right common carotid arteries.

Detailed explanation-3: -Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.

Detailed explanation-4: -The conus arteriosus branch of the right coronary artery (otherwise called the right conus artery or the arteria coni arteriosi) is the first branch of the right coronary artery.

Detailed explanation-5: -The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
