hemorrhage
n. bleeding: any loss of blood from an artery or vein. A hemorrhage may be external, internal, or within a tissue, such as the skin; a bruise is a sign of bleeding within the skin. A hemorrhage from a ruptured artery is bright red in color and erupts in spurts that coincide with heart contractions; it is generally more serious than hemorrhage from a vein, which shows as a relatively slow, steady flow of dark red blood. Brain hemorrhages may arise from head injuries or aneurysms, causing widespread damage in some cases (see cerebral hemorrhage). —hemorrhagic
