What is the function of the coronary arteries?

• To transport oxygen from the lungs to the body.

• To remove waste products from the heart.

• To regulate blood pressure throughout the body.

• Left atrium, right ventricle, body, right atrium, lungs, left ventricle

• Right ventricle, lungs, left atrium, body, right atrium, left ventricle

• The pathway of blood circulation through the heart involves the right atrium, right ventricle, lungs, left atrium, left ventricle, and then to the body.

What role do valves play in the cardiovascular system?

• Valves increase blood pressure in the arteries.

• Valves prevent backflow and ensure unidirectional blood flow in the heart.

• Valves control the heart rate and rhythm.

• Valves are responsible for oxygenating the blood.
