Verified step by step guidance

Understand the concept of pulmonary circulation: Pulmonary circulation is the process by which deoxygenated blood is transported from the heart to the lungs for oxygenation and then returned to the heart.

Identify the chambers of the heart: The heart has four chambers—right atrium, right ventricle, left atrium, and left ventricle. Each chamber has a specific role in blood circulation.

Determine the role of the right ventricle: The right ventricle pumps deoxygenated blood into the pulmonary arteries, which carry it to the lungs for oxygenation.

Eliminate incorrect options: The right atrium receives deoxygenated blood from the body, the left atrium receives oxygenated blood from the lungs, and the left ventricle pumps oxygenated blood to the rest of the body. None of these chambers are directly involved in sending blood to the lungs during pulmonary circulation.

Conclude that the correct answer is the right ventricle, as it is the chamber responsible for initiating pulmonary circulation by sending blood to the lungs.
