Physiology of the heart and its blood vessels
The heart muscles work non-stop throughout life to contract and pump blood to the various organs of the body. As they are constantly in motion they require regular and adequate supply of oxygen-rich blood to function normally.
Blood to the heart muscles, called cardiac muscles, is supplied by two large blood vessels that are known as the left and right coronary arteries. These originate at the base of the largest artery that arises out of the left ventricle to supply all the organs of the body called the aorta.
