Which chamber pumps oxygenated blood to the systemic circulation?

Explanation:
Systemic circulation relies on the chamber that can generate enough force to push oxygen-rich blood through the entire body. After oxygenated blood returns from the lungs to the left atrium, it moves into the left ventricle. The left ventricle then contracts powerfully, sending blood into the aorta and—the rest of the body—throughout the systemic circulation. Its thick, muscular wall is built for this high-pressure job, unlike the right ventricle, which pumps to the lungs, or the atria, which mainly collect blood. So the chamber that pumps oxygenated blood to the systemic circulation is the left ventricle.
