Which chamber pumps blood to the lungs?

Explanation:
The chamber that sends blood to the lungs is the right ventricle. After blood returns from the body to the heart, it moves from the right atrium into the right ventricle. When the right ventricle contracts, it pushes blood through the pulmonary valve into the pulmonary artery, directing it to the lungs for oxygenation. This arrangement is part of the pulmonary circulation, which loads blood with oxygen before it returns to the left side of the heart. In contrast, the left ventricle pumps oxygenated blood to the entire body via the aorta, while the atria mainly receive blood.
