Label the structures of the heart and describe the flow of blood through it.

here are the labels for the diagram and the functions of blood flow through the heart.

Labels for the Heart Structures:

1. Right Ventricle
2. Left Ventricle
3. Right Atrium
4. Opening of Inferior Vena Cava
5. Inferior Vena Cava
6. Superior Vena Cava
7. Pulmonary Artery (main trunk)
8. Aorta (aortic arch)
9. Left Pulmonary Artery
10. Left Atrium
11. Left Superior Pulmonary Vein
12. Right Pulmonary Artery
13. Right Superior Pulmonary Vein
14. Left Inferior Pulmonary Vein
15. Brachiocephalic Artery
16. Left Common Carotid Artery
17. Left Subclavian Artery
18. Ligamentum Arteriosum
19. Tricuspid Valve
20. Mitral Valve (Bicuspid Valve)
21. Left Atrium
22. Chordae Tendineae / Papillary Muscles
23. Opening of Inferior Vena Cava

Functions of Blood Flow (as there are no arrows on this specific diagram):

1. Deoxygenated blood from the body enters the Right Atrium (via the Superior and Inferior Vena Cava).
2. It then passes through the Tricuspid Valve into the Right Ventricle.
3. The Right Ventricle pumps this deoxygenated blood into the Pulmonary Artery, which carries it to the lungs to pick up oxygen.
4. Oxygenated blood returns from the lungs via the Pulmonary Veins to the Left Atrium.
5. It then passes through the Mitral Valve into the Left Ventricle.
6. The Left Ventricle pumps this oxygenated blood into the Aorta, which distributes it to the rest of the body.
