This is a crucial step in the systemic circulation process. The other choices are incorrect because: A: Right ventricle - The right ventricle pumps deoxygenated blood to the lungs, not oxygen-rich blood. C: Capillaries - Capillaries are tiny blood vessels where gas exchange occurs between blood and tissues, not a site where blood is pumped.
