Where is the pulmonic valve located?

• A. Between left ventricle and aorta
• B. Between right ventricle and pulmonary artery
• C. Between right atrium and right ventricle
• D. Between left atrium and left ventricle

Answer: (B)

Pulmonic valve is one of the heart’s four semilunar valves and sits at the outflow tract from the right ventricle to the pulmonary artery. Its job is to allow blood to flow from the right ventricle into the pulmonary artery during systole and to close during diastole to prevent backflow into the ventricle. So the correct description is the valve between the right ventricle and the pulmonary artery. The other described pairings correspond to the mitral valve (between left atrium and left ventricle) and the tricuspid valve (between right atrium and right ventricle) or the aortic valve (between left ventricle and aorta).
