Which valves are included in the four valves of the heart?

The four valves of the heart are the tricuspid valve, mitral valve (also known as the bicuspid valve), aortic valve, and pulmonic valve. Option B accurately lists these four valves: the tricuspid valve controls blood flow from the right atrium to the right ventricle, the mitral valve regulates blood from the left atrium to the left ventricle, the aortic valve manages blood flow from the left ventricle into the aorta, and the pulmonic valve oversees blood flow from the right ventricle into the pulmonary arteries.

In the context of the other choices, while they may name some correct valves, they either include incorrect terminologies or configurations that do not represent the standard four valves recognized in human anatomy. For instance, the term "semilunar" does not designate a specific valve type but rather refers to a category that encompasses both the aortic and pulmonic valves. Atrioventricular is a general term describing the function rather than naming a specific valve. Thus, the selection of option B is correct as it clearly identifies all four valves of the heart by their proper names.
