Bleeding can occur internally, where blood leaks from blood vessels inside the body, or externally, either through a natural opening such as the vagina, mouth, nose, ear or anus, or through a break in the skin.
Desanguination is a major blood loss. Exsanguination is losing enough blood to cause death. A person does not have to lose all of their blood to die. People can die from losing half to two-thirds of their blood.
