Question

During coronary circulation ____________ supplies oxygenated blood to the heart muscles.

• A. coronary vein
• B. coronary artery
• C. pulmonary vein
• D. pulmonary artery

Answer 1

The correct option is B coronary artery

Coronary circulation is a process by which blood is supplied to the heart muscles. The heart muscles (myocardium) require a continuous supply of oxygen and nutrients in order to function in an efficient manner. The coronary arteries supply oxygenated blood to the heart muscles and the coronary veins carry deoxygenated blood from the heart.

The pulmonary vein carries oxygenated blood from the lungs to the heart. The pulmonary artery carries deoxygenated blood from the heart to the lungs.
