Bleeding is the process where blood escapes from the circulatory system, often due to an injury or damage to blood vessels. This can happen from cuts, scrapes, or more serious wounds. When bleeding occurs, the body works to stop the flow of blood through a process called clotting, which helps prevent excessive blood loss. There are different types of bleeding, such as external bleeding, which is visible outside the body, and internal bleeding, which happens inside the body and may not be immediately noticeable. It's important to seek medical help if bleeding is severe or doesn't stop, as it can lead to serious health issues.
