External hemorrhage refers to the loss of blood from the circulatory system that occurs outside the body. This can happen due to injuries, such as cuts or wounds, where blood vessels are damaged. The severity of external hemorrhage can vary, ranging from minor bleeding that stops on its own to severe bleeding that requires immediate medical attention. Common causes of external hemorrhage include accidents, surgical procedures, or trauma. It is important to control external bleeding quickly to prevent shock or other complications. First aid measures, such as applying pressure to the wound, can help manage the situation until professional help arrives.
