A person who is exposed to high levels of smoke during a fire may be taken to a hospital for a test to determine whether he or she has enough oxygen in the blood. Would you test the blood from an artery or a vein in this case? Explain your answer

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.
