Reasons of Blood Clotting and Nose Bleeding
Blood clotting is the body's way of stopping blood loss. When one gets a cut on the body with a knife or any other sharp object, blood vessels break and blood flows out. These blood vessels could either be an artery or a vein. If an artery has been cut, blood flows out stronger and faster as the pressure comes directly from the heart but if it's a vein then blood spills out slower. The human nose is one of the few parts of our body that has many nerves and blood vessels. It is exposed to dirt and pollutants that's why it produces mucus to filter these pollutants before they reach the airways and the lungs.
A minor cut is forms something like a knot around it. The blood gets exposed to the air so it gets thick and dries up. This has a double purpose, the knot traps blood cells from leaking out and at the same time it also prevents other particles from blending into the bloodstream. Nose bleeding that lasts for minutes can be caused by something more than booger scooping. The reason it bleeds is because blood vessels inside have ruptured through broken skin. Dryness inside may cause the skin to break.
