Heart - Blood Flow

We've now learned about all of the arteries and veins that pump blood all over the body.

The part of the body that does the pumping is the heart, which has 4 chambers that we've already learned about.

Deoxygenated blood comes into the Right Atrium and then goes to Right Ventricle.
The Right Ventricle pushes the blood to the lungs to get oxygen, then the oxygenated blood comes into the Left Atrium.
The blood then goes into the Left Ventricle which sends the blood to all parts of the body, and it comes back to the Right Atrium where we started.

So it goes Right Atrium, Right Ventricle, Lungs, Left Atrium, Left Ventricle, Body, Right Atrium.
