The pulmonary valve, or pulmonary semilunar valve, is made up of three leaflets or cusps. It located at the base of the pulmonary trunk. This valve opens when the right ventricle contracts. When the right ventricular muscles relax, blood starts back up the pulmonary trunk, causing the valve to close to prevent the flow from returning into the ventricular chamber.
