Question

list the path for blood flow through the heart, lungs, and body, beginning and ending in the heart chamber that receives oxygen - poor blood returning from the body. your answer should include the specific heart chambers, the lungs, and the body.

Explanation:

The question asks for the blood flow path starting and ending in the right atrium (which receives oxygen-poor blood from the body). The path follows systemic circulation (body to heart), pulmonary circulation (heart to lungs to heart), and returns to systemic circulation's starting chamber.

Answer:

1. Right atrium (receives oxygen-poor blood from body)
2. Right ventricle
3. Pulmonary arteries
4. Lungs (oxygenation occurs)
5. Pulmonary veins
6. Left atrium
7. Left ventricle
8. Aorta
9. Body tissues (oxygen delivery; blood becomes oxygen-poor)
10. Venae cavae
11. Right atrium (ends here)
