Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?

Question

Quizplus · Accepted Answer

The lungs are the site of gas exchange where oxygen is taken up by red blood cells and carbon dioxide is released. When oxygen levels are low, the body constricts blood vessels in the lungs to maximize the amount of oxygen that is delivered to the tissues. Conversely, when oxygen levels are high, the body dilates blood vessels to allow more blood to flow through and release excess oxygen.
