What’s the purpose in nose bleeds and why do we have them. It seems pretty counterproductive to have what keeps us alive to just leave our body uncontrollably.

Nosebleeds are more of a design flaw than a feature. Your nasal septum (the wall of cartilage between your two nostrils) has a bunch of arteries towards the front of your nose. The purpose of these arteries is to concentrate a lot of blood right in the front of your nose, which warms the air coming in through your nose so your lungs can more quickly absorb the oxygen from it. The downside of this is that even a small nick or crack in the membrane at the surface of your septum can cause heavy bleeding, hence nosebleeds.
