Final answer:
The pulmonary veins are the only option listed that does not deliver deoxygenated blood to the heart; instead, they carry oxygenated blood from the lungs to the left atrium.
Step-by-step explanation:
The component of the circulatory system that does NOT deliver deoxygenated blood to the heart is the pulmonary veins. While the coronary sinus, superior vena cava, and inferior vena cava all carry deoxygenated blood to the right atrium of the heart, the pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the heart, specifically to the left atrium. It is the only one of the options provided that carries oxygenated blood.
The pulmonary veins deliver oxygenated blood to the heart, not deoxygenated blood. The pulmonary veins carry blood from the lungs back to the left atrium of the heart, where it is then pumped to the rest of the body. On the other hand, the coronary sinus, superior vena cava, and inferior vena cava all deliver deoxygenated blood to the heart.
