Question

Why do mountaineers usually suffer from nose-bleeding at high altitudes ?

Answer 1

• As the altitude increases the atmospheric pressure decrease. And the air becomes thinner and there will be very less oxygen at high altitude.
• As the altitude increases the atmospheric pressure decrease. And the air becomes thinner and there will be very less oxygen at high altitude.So due to which the blood vessels present inside our their nose bursts and starts bleeding. This is why mountaineers suffer from nose bleeding!

Please mark it the brainliest answer.

Thank You

Answer 2

Blood pressure vs. Atmospheric pressure

Explanation:

Our body has a liquid called blood which flows through the blood vessel into each and every cell of our body. Our blood itself exerts a pressure called blood pressure, which is slightly greater than the atmospheric pressure. Since the atmospheric pressure acting on our body is balanced by the blood pressure acting from inside, we do not get crushed.

When you go to higher altitudes, atmospheric pressure decreases. This causes the blood pressure to be very much higher than the outside atmospheric pressure. So sometimes, the blood vessels in the nose burst due to the high pressure inside our body, causing a nose-bleed.
