The aortic valve does that job.
The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
No the heart pumps the blood but it does pump the blood through the arteries.
the heart!
Blood vessels have valves that act like doors really. Also blood is pumped (pushed) out and around your body by each pump of your heart, each pump pushes more blood through, there is nowhere else to go but forward. It doesn't suck it back .

the heart and muscles
It is necessary for blood to pump through your body because it keeps you alive. It sends the blood to your organs and keeps them from failing.
Your heart contracts, forcing your blood out your aorta, and through your body.
2 of these valves (one on each side) stop blood from flowing back into the atria chambers of the heart when the heart is contracting and expelling blood. The other two are there to stop blood flowing out of the ventricles when the heart is filling up with blood. One stops blood flowing through the aorta to supply the body and the other stops it flowing through the pulmonary artery to the lungs.
