The heart has 4 chambers. Each of these chambers plays an important role in the circulation blood through heart. List them order flow heart?

The four chambers of the heart, in order of blood flow, are:

1. The superior and inferior vena cava: These two large veins carry deoxygenated blood from the body back into the heart.

2. The right atrium: The right atrium is the first chamber of the heart that the deoxygenated blood enters.

3. The tricuspid valve: The tricuspid valve separates the right atrium from the right ventricle. It opens to allow blood to flow from the atrium to the ventricle.

4. The right ventricle: The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the lungs.

5. The pulmonary valve: The pulmonary valve separates the right ventricle from the pulmonary artery. It opens to allow blood to flow from the ventricle to the lungs.

6. The pulmonary arteries: The two pulmonary arteries carry the deoxygenated blood from the heart to the lungs.

7. The lungs: In the lungs, the deoxygenated blood picks up oxygen and becomes oxygenated.

8. The pulmonary veins: The four pulmonary veins carry the oxygenated blood from the lungs back into the heart.

9. The left atrium: The left atrium is the first chamber of the heart that the oxygenated blood enters.

10. The mitral valve: The mitral valve separates the left atrium from the left ventricle. It opens to allow blood to flow from the atrium to the ventricle.

11. The left ventricle: The left ventricle is the chamber of the heart that pumps the oxygenated blood to the body.

12. The aortic valve: The aortic valve separates the left ventricle from the aorta. It opens to allow blood to flow from the ventricle to the body.

13. The aorta: The aorta is the largest artery in the body. It carries the oxygenated blood from the heart to the body.
