THE HEART AS A PUMP-CARDIOVASCULAR SYSTEM TUTORIAL
The Right and Left Hearts are Connected in Series, but are Folded Together to Form a Single Unit
- The right heart pumps blood only to the lungs; its output is low pressure (25 mm Hg)
- The left heart pumps blood to the rest of the body; its output is high pressure (120 mm Hg)
- Because the 2 hearts are attached they beat in synchrony
- The 2 atria receive the incoming blood- they pump extra blood into the ventricles
