As a cardiac specialist with extensive knowledge in the field of cardiology, I can confidently explain the function of the heart's chambers and the flow of blood within it. The heart is a muscular organ that pumps blood throughout the body, and it is divided into four chambers: two atria and two ventricles. The left ventricle is the strongest and largest chamber of the heart, and it is responsible for pumping oxygen-rich blood to the rest of the body.

The process begins with oxygen-poor blood returning to the right atrium from the body. This blood then moves to the right ventricle, which pumps it to the lungs where it picks up oxygen and releases carbon dioxide. The now oxygen-rich blood returns to the heart, entering the left atrium, and from there, it flows into the left ventricle. The left ventricle then contracts, sending this oxygen-rich blood out through the aorta to supply the entire body with the oxygen and nutrients it needs.

So, to answer your question, the left ventricle of the heart pumps oxygen-rich blood to the body.
