Question

Heart attack involves a blockage of the _______________.

• A. Carotid artery
• B. Aorta
• C. Pulmonary vein
• D. Coronary arteries

Answer 1

The correct option is D Coronary arteries

• The heart is a muscular pump, that needs a continuous supply of oxygen.
• It gets oxygen from the blood, which flows to the heart muscle through arteries on its surface. These arteries are called coronary arteries.
• A heart attack happens, when there is a sudden complete blockage of an artery that supplies blood to an area of the heart.
• As a result, some of the heart muscle begins to die.
