Question

Why does nose start bleeding on high mountains?

• A. pressure inside body > atmosphere pressure
• B. pressure inside body < atmosphere pressure
• C. pressure inside body = atmosphere pressure
• D. None of the above reason is correct

Answer 1

The correct option is A pressure inside body > atmosphere pressure

We know that atmospheric pressure decreases with high altitude.
So, at higher altitude atmospheric pressure is lower compared to the pressure at the surface.
At higher altitudes the blood pressure inside our body is more than the atmospheric pressure which forces the blood to ooze out from openings like the nose. Hence the nose bleeding.
