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 vagina, mouth, nose, ear or anus, or through a break in the skin.

Desanguination is a massive blood loss, and the complete loss of blood is referred to as exsanguination.[2] 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.[3]
