Which chamber pumps blood to the body?

Right Ventricle Right Atrium Left Ventricle Left Atrium

Correct Answer:

Left Ventricle

Explanation:

The left ventricle is the chamber that sends blood to the body. It receives oxygen-rich blood from the left atrium and then contracts with high pressure to eject it into the aorta, sending it through the systemic circulation to all tissues. Its thick, muscular wall is built for this job, providing the force needed to overcome the body’s resistance. The right ventricle, in contrast, pumps blood to the lungs for oxygenation, while the atria mainly receive blood and feed it to the ventricles.
