contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent the backflow of blood. There are four heart valves within the heart: ...
The heart has four chambers and four valves. The top two chambers (atria) receive blood and the bottom two (ventricles) pump blood out. The valves open to allow blood to flow through and close so that blood can't flow backward. And all of this happens within one heartbeat. Heart ...
On the outside, the heart is made of muscle. The strong muscular walls contract (squeeze), pumping blood to the arteries. The cardiovascular system is made up of your heart and your blood vessels. This heart anatomy diagram shows that blood flows from the right atrium into the right ventric...

The blood from the umbilical vein that does not flow through the ductus venosus enters the fetal liver via the portal vein. The blood from the IVC enters the heart via the right atrium. The foramen ovale is an opening between the right and left atria allowing most of the blood bypass the...
