Question

Nose bleeds occur at high altitude because ______.
A The atmospheric pressure becomes much more than our blood pressure
B Our blood is at a higher pressure than the outside pressure
C Our blood is at lower pressure than the outside pressure
D None of these​

Answer 1

Answer:

C) c is correct

Explanation:

when our blood pressure is there we don't know about atmospheric pressure but when it is low we can have things like bleeding

Answer 2

B.Our blood is at higher pressure than the outside 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.
