The statement that pulmonary circulation transports blood to and from the lungs for oxygenation is accurate because this type of circulation specifically refers to the pathway that carries deoxygenated blood from the right side of the heart to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, and the now oxygenated blood is returned to the left side of the heart. This process is crucial for maintaining the body’s oxygen supply and removing carbon dioxide, ensuring proper respiratory function.

In contrast to this, systemic circulation involves the transport of oxygenated blood from the left side of the heart to the rest of the body, which relates to the first and fourth choices. The third choice correctly describes a portion of the pulmonary circulation process (the movement of deoxygenated blood to the lungs), but the most comprehensive statement regarding the overall role of pulmonary circulation is the one about its function in transporting blood to and from the lungs for oxygenation.
