A patient's blood oxygen saturation level is 99% on room air. The nurse realizes that the oxygenated blood is transported to the heart through which structure?
1. pulmonary arteries
2. pulmonary veins
3. bronchial arteries
4. bronchial veins
Correct Answer: 2
The vascular system of the lungs consists of the pulmonary arteries, which deliver blood to the lungs for oxygenation; and the pulmonary veins, which deliver oxygenated blood to the heart. Bronchial arteries and veins are located within the lungs and are not directly involved with transporting oxygenated blood to the heart.
