Which chamber is primarily responsible for pumping blood to the body?

Explanation:
The left ventricle is the chamber that drives blood into the systemic circulation to nourish the whole body. Its muscular wall is the thickest of the heart’s chambers, built to generate the high pressure needed to push oxygen-rich blood through the aorta and out to all tissues. The right ventricle, by contrast, sends blood to the lungs at a much lower pressure, which is why it has a thinner wall. The atria mainly act as receiving chambers, channeling blood into the ventricles rather than printing the force to push blood to the body. So, the left ventricle’s job is pumping blood to the body.
