Yes, there are two labels for 19 and for 20 in the picture,
to show that the label applies to more than one spot.




cardiac blood flow
BLOOD FLOW THROUGH THE HEART

1. Deoxygenated blood from the body goes to the vena cava
2. The blood enters the right atrium
3. The blood is pumped into the right ventricle
4. The (still) deoxygenated blood is pumped into the pulmonary arteries
5. The blood is oxygenated in the lungs, and returns through the pulmonary veins
6. The oxygenated blood enters the left atrium
7. The blood is pumped into the left ventricle
8. The blood is pumped into the aorta, where it goes to the body

Look at numbers 4 and 5, where DEOXYGENATED blood travels through the arteries and OXYGENATED blood travels through the veins (opposite of what happens in the rest of the body). This always finds its way onto an anatomy exam, where the question is a variation of "Where does oxygenated blood flow through the veins?" or "Do arteries only carry deoxygenated blood?"
