This document summarizes gear and physiological adaptations needed for climbing mountains at high altitudes. It lists essential climbing gear like boots, helmets, tents, ropes, sunglasses, oxygen tanks, and additional equipment for snow conditions such as crampons, ice axes, snow shovels, and avalanche beacons. It also describes how the human respiratory system adapts with larger lungs and ability to function with thin air and little oxygen, along with a more effective circulatory system and barrel-shaped chest and shorter height of the skeletal system.
