Label the parts of the mammalian heart and describe their function.

Here are the names of the labeled parts of the mammalian heart:

1. Aorta (carries oxygenated blood from the left ventricle to the body)
2. Pulmonary artery (carries deoxygenated blood from the right ventricle to the lungs)
3. Vena Cava (specifically, the superior vena cava, which brings deoxygenated blood from the upper body to the right atrium)
4. Pulmonary veins (carry oxygenated blood from the lungs to the left atrium)
5. Left Atrium (receives oxygenated blood from the pulmonary veins)
6. Right Atrium (receives deoxygenated blood from the vena cava)
7. Right Ventricle (pumps deoxygenated blood to the pulmonary artery)
8. Left Ventricle (pumps oxygenated blood to the aorta)
