Answer:
what I have to answer here nothing as afast
The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.
However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs.
From what I know, Its simply an outside force that kills an unsuspecting population, so do with that as you will, im only a highschool fetus
