The atmosphere that we breathe is about 21% oxygen, and our respiratory system has evolved to allow us to thrive at that concentration. However, breathing air with a lower concentration of oxygen is difficult for us, or even fatal (although some other animals can do it). Using your knowledge of normal human respiration, describe two specific modifications to our respiratory system that might improve our respiratory function and allow us to survive at lower oxygen levels (hint: think about things like diffusion, surface area, and oxygen-carrying ability).
