The heart


The heart contracts to pump blood around the body The heart consists of a

right side and a left side.

Both sides have   an atria and a ventricle Blood flows into the atria and then

enters the ventricle.

When  the heart contracts the blood flows out of the atria and  enters the

ventricles and the second contraction allows blood  to go from the ventricles

to the destination. The blood from the right ventricle goes to the lungs to get

oxygenated and the blood from the left ventricle goes to the rest of the body.
