Hemorrhages refer to the loss of blood from the circulatory system, which can occur internally or externally. They can result from various causes, including injuries, medical conditions, or surgical complications. The severity of a hemorrhage can vary, with some being minor and others potentially life-threatening. There are different types of hemorrhages, such as arterial, venous, and capillary hemorrhages, each classified by the type of blood vessel involved. Symptoms may include swelling, bruising, or visible blood loss, and treatment often involves controlling the bleeding and addressing the underlying cause.
