Solution

The correct answer is "left ventricle; right atrium".

Here's why:

  1. The oxygen-rich blood is pumped out of the heart to the rest of the body from the left ventricle. This is the strongest chamber of the heart, capable of pushing the blood into the systemic circuit, which is the system of blood vessels that carries blood from the heart to the body and back.

  2. After the oxygen in the blood has been used up by the body's tissues, the now oxygen-poor blood returns to the heart. It first enters the right atrium, which is the chamber of the heart that receives deoxygenated blood from the body through the veins.

So, the oxygen-rich blood in the systemic circuit leaves the left ventricle of the heart via arteries. The veins return blood to the right atrium of the heart to complete the circuit.
