QUESTION:

The myocardium receives its blood supply directly from the

(a) aorta

(b) coronary arteries

(c) coronary sinus

(d) pulmonary arteries

ANSWER:

Step 1 of 2

Aorta, the largest artery in the body, carries oxygen-rich blood from the left ventricle to the rest of the body. However, its main role is to transport blood to the body's systemic circulation, not to directly nourish the heart's muscle, the myocardium.
