What does the left ventricle do?

Pumps deoxygenated blood to the lungs
Pumps oxygenated blood to the body
Receives blood from the right atrium
Filters blood for the heart

The correct answer is: Pumps oxygenated blood to the body

The left ventricle is responsible for pumping oxygenated blood throughout the body, making it essential for delivering the necessary nutrients and oxygen to the tissues and organs. After receiving oxygen-rich blood from the lungs via the pulmonary veins, the left ventricle contracts and propels this blood into the aorta, which is the main artery that carries oxygenated blood to the systemic circulation. Understanding the function of the left ventricle is crucial in comprehending the heart's overall role in maintaining proper circulation. Its robust muscular wall allows it to generate the high pressure required to distribute blood efficiently over various distances in the body, differentiating its action from that of other chambers of the heart, such as the right ventricle, which pumps deoxygenated blood to the lungs for oxygenation.
