What is the Right Ventricle?
Is the contraction phase of the cardiac cycle.
What is the systole?
Normal average arterial blood pressure.

What is the Pulmonary Artery?
The type of circulation that carries blood to and from the lungs.
What is Pulmonary Circulation?
Is the amount of blood that one ventricle can eject each minute.
