What do coronary arteries supply?

• A. The lungs
• B. The myocardium
• C. The brain
• D. The liver

Answer: (B)

Coronary arteries are specifically responsible for supplying blood to the myocardium, which is the muscular layer of the heart. This is crucial because the myocardium requires a continuous supply of oxygen and nutrients to function effectively and to maintain the heart's pumping ability. The coronary artery system branches off from the aorta and encircles the heart, ensuring that all areas of the heart muscle receive adequate blood flow. The health of the coronary arteries is vital, as any blockage or impairment can lead to conditions such as angina or myocardial infarction (heart attacks). Understanding the role of the coronary arteries can help in recognizing cardiovascular health issues and the importance of maintaining good heart health.
