MICROANATOMY

Detailed explanation-1: -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-2: -The heart is highly metabolically active and boasts the highest oxygen consumption by mass of any organ. This demand for oxygen is met by the coronary circulation, which is responsible for delivering blood to the myocardium and represents approximately 5% of cardiac output.

Detailed explanation-3: -The function of the coronary arteries and their branches is to supply your heart with blood. Your heart muscles need the oxygen and nutrients in blood so they can pump blood through your heart and the rest of your body.

Detailed explanation-4: -The coronary arteries are responsible for carrying nutrient-rich, oxygenated blood from the left ventricle to the myocardium; while the coronary veins take nutrient – poor deoxygenated blood away from the myocardium and to the right atrium.

Detailed explanation-5: -Your heart is the most important muscle as it pumps blood all over your body. To work properly, it needs a continuous blood supply. Coronary arteries are the blood vessels that supply your heart muscle with its blood. This blood is full of oxygen, which is needed by every cell in your body.
