Answer:

Nose bleeding or epistaxis occurs when a person climbs up mountains due to

LOW PRESSURE.

Let me explain why:

Now, as a person climbs up a mountain, the ambient pressure goes on decreasing.

Whereas, the blood pressure inside the blood vessels remain constant and relatively high due to pumping of the heart.

This pressure difference leads to minor rupture of arteries present in the nose lessons to bleeding from the nose.

ADDITIONAL INFORMATION ON NOSE BLEEDING:

The arteries that undergo rupture in nose bleeding are

1. Anterior ethmoidal artery

2. Posterior ethmoidal artery

3. Sphaenopalatine artery

4. Greater Palatine artery.
