Bleeding
Bleeding, technically known as haemorrhaging (Brit.) or hemorrhaging (US) is the loss of blood or blood escape from the circulatory system.[1]
Bleeding can occur internally, where blood leaks from blood vessels inside the body, or externally, either through a natural opening such as the 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.[2] 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.[3]
Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties, and blood donation typically takes 8–10% of the donor's blood volume.[4]
