Which chamber of the heart is responsible for pumping blood to the lungs?

The chamber of the heart responsible for pumping blood to the lungs is the right ventricle. This chamber receives deoxygenated blood from the right atrium, which comes from the systemic circulation. Once the right ventricle fills with this blood, it contracts and sends the blood through the pulmonary arteries to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, allowing the blood to become oxygenated before it returns to the heart.

The left ventricle, on the other hand, is responsible for pumping oxygenated blood out to the rest of the body, which is a separate function from that of the right ventricle. The left atrium receives oxygen-rich blood from the lungs, while the right atrium gathers deoxygenated blood from the body and directs it to the right ventricle. Therefore, the right ventricle's primary function is crucial for pulmonary circulation, highlighting its importance in the overall cardiovascular system.
