Question

Which is responsible for transporting oxygen-poor blood from the upper part of the body to the right atrium of the heart?

inferior vena cava

superior vena cava

pulmonary veins

pulmonary arteries

Answer 1

Answer: The superior vena cava.

Step-by-step explanation:

If you want to get particular, the superior vena cava is formed by the meeting of two veins: the brachiocephalic veins. Because it is a vein, the superior vena cava does not protrude from the heart but instead goes back to it due to how arteries leave the heart and veins go to the heart. Hope this helps!
