Verified step by step guidance

Step 1: Understand the anatomy of the heart and the flow of blood through its chambers. The aorta is the largest artery in the body and carries oxygenated blood away from the heart to the rest of the body.

Step 2: Recall that the aorta is connected to the left ventricle of the heart. Blood is pumped from the left ventricle into the aorta during systole (the contraction phase of the heart).

Step 3: If a probe is inserted into the aorta and followed backward, it will trace the path of blood flow in reverse. This means the probe will move from the aorta into the left ventricle.

Step 4: Eliminate the other options based on the anatomy of the heart. The right atrium and right ventricle are part of the pulmonary circulation, which deals with deoxygenated blood returning to the lungs. The left atrium receives oxygenated blood from the lungs but does not connect directly to the aorta.

Step 5: Conclude that the probe will exit the left ventricle, as this is the chamber directly connected to the aorta.
