Hemorrhage

Hemorrhage
Bleeding or the abnormal flow of blood. The patient may have an internal hemorrhage that is invisible or an external hemorrhage that is visible on the outside of the body. Bleeding into the spleen or liver is internal hemorrhage. Bleeding from a cut on the face is an external hemorrhage. The term "hemorrhagic" comes from the Greek "haima," blood + rhegnumai," to break forth = a free and forceful escape of blood.
