ANATOMY

Detailed explanation-1: -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. Two main coronary arteries originate from the base of the aorta as it exits the left ventricle: the left and right coronary arteries.

Detailed explanation-2: -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-3: -The coronary arteries supply the heart with oxygen and other nutrients.

Detailed explanation-4: -The coronary arteries are the first vessels to branch from the aorta, and they provide a crucial supply of oxygen and nutrients to the layers of the heart.
