Pulmonary Valve

We've now learned about three of the four heart valves:
The tricuspid valve between the right atrium and ventricle,
the mitral valve between the left atrium and ventricle,
and the Aortic Valve between the left ventricle and aorta.

The fourth valve is the pulmonary valve, between the right ventricle and pulmonary artery.
When the right ventricle pushes the pulmonary valve open, the blood goes from the heart to the lungs for oxygen.
