Which term refers to the arteries that supply blood to the heart muscle?

• A. Nitroglycerin
• B. Coronary Arteries
• C. Atherosclerosis
• D. Cardiac Tamponade

Answer: (B)

The arteries that supply blood to the heart muscle are the coronary arteries. They originate from the base of the aorta and run over the heart’s surface, branching to reach every region of the myocardium so the heart receives the oxygen and nutrients it needs to pump effectively. When these vessels narrow or become blocked, the heart muscle can suffer from insufficient blood flow, leading to chest pain or a heart attack. Nitroglycerin is a drug that dilates blood vessels to relieve chest pain, not the vessels themselves. Atherosclerosis is the process of plaque buildup within arteries, which can affect the coronary arteries but isn’t the term for the vessels. Cardiac tamponade is a condition where fluid around the heart compresses it, impeding pumping, not related to the coronary arteries themselves.
