Valves in the heart include Tricuspid, Pulmonary, Mitral (Bicuspid), Aortic.

• A. Aortic, Pulmonary, Coronary, Jugular
• B. Tricuspid, Aortic, Semilunar, Coronary
• C. Tricuspid, Pulmonary, Mitral (Bicuspid), Aortic
• D. Mitral, Pulmonary, Jugular, Carotid

Answer: (C)

Understanding the four heart valves and where they sit is what this question tests. The heart has four valves that ensure blood flows in one direction: tricuspid between the right atrium and right ventricle; pulmonary at the outlet of the right ventricle into the pulmonary artery; mitral (bicuspid) between the left atrium and left ventricle; and the aortic valve at the outlet of the left ventricle into the aorta. Together these four names—tricuspid, pulmonary, mitral (bicuspid), and aortic—form the complete set. The other options mix in structures that aren’t valves. Coronary refers to the arteries supplying the heart muscle, not a valve. Jugular and carotid are neck vessels, not valves. Semilunar describes the type of valves for the heart’s outflow (pulmonary and aortic) but doesn’t name all four valves, whereas the correct list provides the exact four valves.
