Has three flaps that open and close, allowing blood to flow from RA to RV
Receives oxygenated blood from the lungs and pumps it down to LV
It separates the LA from the LV; it prevents the blood flowing backward
It is the thickest chambers and responsible for pumping oxygenated blood to the tissue all over the body

This system is made of the heart, veins, and arteries
The heart pumps blood to the body reaching the toes and fingers. This is called:________
I take blood towards the heart.
I take blood away from the heart to the parts of the body that need oxygen.
