Under the bleeding is commonly understood as steppingblood outside the vascular bed. If blood flows into the environment, referred to as external bleeding, if permeates tissue, flows into the body cavity, it is called internal.

- When propotevanie (diapedesis) through intact blood vessels, which may be due either to increased permeability of the vascular walls, or to changes in the composition of the blood itself.
The most common cause of blood from the noseis damage to blood vessels of the anterior nasal septum (Kisselbaha place), densely penetrated by a network of small arterioles and capillaries. Violation of the integrity of the blood vessels occurs in injuryOften at inaccurate removal of dry crusts, rough scratching and blowing nose nose. Such bleeding is usually not a threat to human health. Blood flows from the nose drops or a thin stream and, under normal coagulation, quickly stopped themselves.
