RELAXES
(diastole)
Blood comes to the right side of the heart from the lower and upper body.
Blood fills the right atrium.
From the right atrium, blood falls through a valve (tricuspid) into the right ventricle.

TIGHTENS
(systole)
The tricuspid valve closes, and the pulmonary valve opens.
Blood is pumped from the right ventricle through the pulmonary valve to the lungs.
