Blood Flow through the Heart

1.It begins by bringing oxygen-rich blood from the lungs into the left atrium.

2.Then the blood moves through the mitral valve and into the left ventricle.

3.From the left ventricle it moves through the aortic valve.

4.From the aortic valve it goes to the aorta, which then sends the blood throughout the entire body.

5.The body uses up all the nutrients and oxygen from the blood and returns it to the heart into the superior and inferior vena cava.

6.From there the blood goes into the right atrium and through the tricuspid valve.

7.After moving the tricuspid valve the blood then enters the right ventricle.

8.Then the blood moves through the pulmonary valve into the pulmonary artery.

9.The pulmonary artery then sends the blood to the lungs to become full of oxygen again and it is sent back into the heart into the left atrium.

10.The blood has now completely circulated through the entire body.
