A hemorrhage is the loss of blood from the circulatory system, which can occur internally or externally. It can result from various causes, including injury, surgery, or medical conditions like hemophilia. The severity of a hemorrhage can vary, with minor bleeding often being manageable, while severe cases can lead to shock or even death. When a hemorrhage occurs, the body may respond by constricting blood vessels and activating clotting mechanisms to minimize blood loss. Treatment options depend on the cause and severity, ranging from applying pressure to a wound to surgical interventions or blood transfusions in critical situations.
