Atherosclerosis affects:

• B. The vessels which supply blood to brain
• C. The vessels which supply blood to lungs
• D. The vessels which supply blood to heart

Answer 1

The correct option is D The vessels which supply blood to heart

Coronary circulation is the circulation of blood through the coronory blood vessels, where oxygenated blood is supplied to the heart.

The coronary arteries are the blood vessels which transport oxygenated blood to the heart muscles. The blockage or narrowing of these arteries is called coronary artery disease or atherosclerosis. Atherosclerosis is caused by the deposition of calcium, fat, cholesterol and fibrous tissue due to which lumen of the arteries gets narrower.
