What is the primary function of coronary arteries?

Supply oxygen-rich blood to the brain
Deliver oxygenated blood to the lungs
Provide blood flow to the heart muscle
Transport deoxygenated blood to the heart

The correct answer is: Provide blood flow to the heart muscle

The primary function of coronary arteries is to provide blood flow to the heart muscle. These arteries are crucial because they branch off from the aorta and supply oxygenated blood directly to the heart tissue. The heart, being a muscle that requires a constant supply of oxygen to function effectively, relies on the coronary arteries to meet this demand. If the blood flow through these arteries becomes restricted or blocked, it can lead to significant problems such as ischemia (insufficient blood supply), angina (chest pain), or even a heart attack. Thus, optimal function of the coronary arteries is essential for maintaining the overall health of the cardiovascular system.
