Which chamber pumps blood to the systemic circulation?

Explanation:
Pumping blood to the systemic circulation requires generating high pressure to push oxygenated blood through the aorta to the whole body. The left ventricle does this with its thick, muscular wall that contracts forcefully to propel blood into the aorta. Blood then travels to body tissues and returns to the heart via the right atrium. The right ventricle, by contrast, sends blood to the lungs for oxygenation at a much lower pressure. Atria mainly receive blood and pass it to the ventricles. So, the chamber that pumps blood to the systemic circulation is the left ventricle.
