Question

What, exactly, happens to the body of the climbers in “The Death Zone” (i.e. on Mount Everest) that causes their death?

In: Biology

Answer 1

There is not enough oxygen in the air at that altitude to keep a human alive. Climbers carry oxygen in bottles, to supplement the air they breathe. Without enough bottled oxygen, they suffocate.
