What is happening to rock climbers' body systems and cells at the small scale

here's your molecular biology answer

Explanation:

At a cellular scale, a lot of things will simultaneously occur to a rock climber. The first being in their respiratory system; since as they climb higher, they enter different levels of our stratosphere (different levels of O2, CO2) which they are not accustomed to. This can make it very hard for them to breathe, which is why a lot of professional climbers will go up there with oxygen masks and emergency supplies so they can prevent lung damage!
