The correct answer encompasses the four main valves that are crucial for the proper functioning of the human heart. These valves include the tricuspid valve, which is located between the right atrium and the right ventricle, and the mitral valve, situated between the left atrium and the left ventricle. The aortic valve controls blood flow from the left ventricle into the aorta, while the pulmonary valve regulates blood flow from the right ventricle into the pulmonary artery.

This combination of valves plays a pivotal role in maintaining unidirectional blood flow through the heart and into the circulation, thereby ensuring efficient transportation of oxygenated and deoxygenated blood throughout the body. The tricuspid and mitral valves are known as atrioventricular valves due to their locations, while the aortic and pulmonary valves are referred to as semilunar valves due to their crescent-shaped flaps.

The other choices include valves that are not part of the human heart (such as subclavian and iliac valves) and thus do not accurately represent the valves present in the cardiovascular system.
