Question

the two lower parts of the heart that pump blood out to the body are called the left and right
bronchi
atria
ventricles

Explanation:

To solve this, we analyze the options:

• Bronchi are part of the respiratory system (air passages in lungs), not the heart.
• Atria are the upper chambers of the heart that receive blood, not pump it out.
• Ventricles are the lower chambers of the heart responsible for pumping blood out to the body (left ventricle to the body, right ventricle to the lungs).

Answer:

ventricles
