What is the primary function of the coronary arteries?

• A. To carry blood away from the heart.
• B. To supply blood, oxygen, and nutrients to the heart muscle.
• C. To drain waste products from the heart.
• D. To regulate blood pressure.

Answer: (B)

The primary function of the coronary arteries is to supply blood, oxygen, and nutrients to the heart muscle. These arteries branch directly from the aorta and encircle the heart, ensuring that the myocardial tissue, which requires a constant supply of oxygen to function effectively, receives adequate blood flow. The heart is a muscular organ that continually pumps blood throughout the body, and its own muscle requires nourishment and oxygen to sustain this activity. When there are blockages or issues with the coronary arteries, it can lead to ischemia, where the heart muscle is deprived of the oxygen it needs, potentially resulting in angina or a heart attack. Therefore, the correct understanding of the coronary arteries' role is crucial in cardiovascular health and disease management.
