"Bleed" refers to the process where a liquid, often blood, escapes from a vessel or body. This can occur due to injury, surgery, or medical conditions. In a broader context, "bleed" can also describe the way ink spreads beyond the intended area in printing, ensuring that there are no white edges when the paper is trimmed. In the medical field, bleeding can be classified as external or internal. External bleeding is visible and occurs outside the body, while internal bleeding happens within the body and may require imaging techniques for diagnosis. Proper management of bleeding is crucial in emergency situations to prevent shock or other complications.
