Question

lo 3.5. what is the function of the coronary arteries?
supply blood to the heart muscle
regulate heart rate
supply blood to the lungs
transport oxygen to the lungs
supply blood to the brain

Explanation:

The coronary arteries are blood vessels that branch off from the aorta. Their main function is to supply oxygen - rich blood to the heart muscle (myocardium). The heart muscle, like any other tissue, needs a continuous supply of oxygen and nutrients to function properly.

• "Regulate heart rate" is mainly the function of the nervous system (such as the autonomic nervous system) and some hormonal mechanisms.
• "Supply blood to the lungs" is the function of the pulmonary arteries.
• "Transport oxygen to the lungs" is related to the respiratory system (e.g., inhalation process) and the pulmonary circulation in a broader sense, but not the coronary arteries.
• "Supply blood to the brain" is the function of arteries like the carotid arteries and vertebral arteries.

Answer:

Supply blood to the heart muscle
