Question

Which series depicts the correct order that the blood flows through the heart?

A. inferior and superior vena cava, left atrium, left ventricle, right atrium, right ventricle, body, lungs
B. right atrium, right ventricle, left atrium, left ventricle, lungs, aorta artery, body
C. inferior and superior vena cava, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta artery, body
D. body, left atrium, right atrium, left ventricle, lungs, right ventricle, aorta artery, inferior and superior vena cava

Answer 1

The correct order that the blood flows through the heart is: inferior and superior vena cava, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta artery, body.

Step-by-step explanation:

The correct order that the blood flows through the heart is:

Option C: inferior and superior vena cava, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta artery, body

Here is the step-by-step flow:

1. Deoxygenated blood enters the right atrium through the inferior and superior vena cava.
2. The blood flows from the right atrium into the right ventricle through the tricuspid valve.
3. From the right ventricle, the blood is pumped through the pulmonary valve into the pulmonary artery.
4. The pulmonary artery carries the blood to the lungs.
5. In the lungs, the blood receives oxygen and gets rid of carbon dioxide through the process of gas exchange.
6. The oxygenated blood returns to the heart through the pulmonary veins, specifically the left atrium.
7. The blood flows from the left atrium into the left ventricle through the mitral valve.
8. From the left ventricle, the blood is pumped out of the heart through the aortic valve into the aorta.
9. The aorta carries the oxygenated blood to the rest of the body.
