Question

when mountaineers climb higher , their nose may start bleeding that's why

Answer 1

hello friend,

mostly the mountaineers climb higher theynose may bleed because of less amount of oxygen in air...

Answer 2

This happens because, when a person is on higher altitude the air pressure decreases but the blood pressure of our body remains constant and because of higher pressure of air the blood cell could not bear that and they bursts out. That is the reason why our nose and ear starts bleeding on higher altitude.
