In most of the body, when tissues are low on oxygen, blood vessels open up (dilate) to bring more oxygen. But in the lungs, the opposite happens: low oxygen makes small arteries narrow (constrict). Why? Because the lung’s job is to match airflow (ventilation) with blood flow (perfusion). If one area of the lung isn’t getting air, it makes no sense to send blood there — that blood would leave still “blue” and waste circulation.
