The _____________ of the heart pumps oxygen-poor blood to the lungs.

The right ventricle of the heart is responsible for pumping oxygen-poor blood to the lungs. This is a critical part of the circulatory system, as it ensures that blood depleted of oxygen is sent to the lungs, where it can release carbon dioxide and absorb fresh oxygen.

After the right atrium collects the deoxygenated blood from the body, it passes this blood into the right ventricle. The contraction of the right ventricle then propels the blood into the pulmonary arteries, which lead to the lungs. In the lungs, blood undergoes a process of gas exchange, receiving oxygen and releasing carbon dioxide before returning to the left side of the heart to be pumped out to the rest of the body.

Understanding the role of each chamber of the heart is crucial for recognizing how blood circulation operates, particularly the distinction between pumping oxygen-rich blood to the body versus directing oxygen-poor blood to the lungs.
