If you place a probe in the aorta into what chamber will it exit?

If you place a probe in the aorta, it will exit into the left atrium. The aorta is the main artery that carries oxygenated blood away from the heart, specifically from the left ventricle. As blood flows from the aorta, it does not directly exit into another chamber; instead, it distributes throughout the body. However, if considering the flow direction back to the heart, blood returns to the left atrium via the pulmonary veins after circulating through the body.
