When I get a nosebleed I immediately pinch my nostrils closed and after about 3 minutes I let go and the bleeding has stopped and there is no blood piled up in my nostril? Where has the blood gone?
In: Biology
You squeeze the tiny blood vessels shut, which keeps them from leaking. It lets the blood in the area sit still long enough to form little tiny clots, which lets the bleed stop. Imagine a water hose out in the freezing temps. It won’t freeze shut easily if it’s running. But if you kink it shut for a while, the end of it can freeze over.
