What is the pulmonary valve's location?

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

Answer: (B)

The pulmonary valve is located between the right ventricle and the pulmonary trunk. It is a semilunar valve that opens when the right ventricle contracts to send blood into the lungs, and closes as the ventricle relaxes to prevent backflow into the heart. This position distinguishes it from the mitral valve (between left atrium and left ventricle), the tricuspid valve (between right atrium and right ventricle), and the aortic valve (between left ventricle and the aorta).
