Bandages are strips of material used to cover and protect wounds on the body. They help keep dirt and germs out, which can prevent infections. Bandages come in various types, such as adhesive bandages, gauze pads, and elastic wraps, each designed for different kinds of injuries. They are essential in first aid kits and are often used by nurses and doctors in hospitals. When applying a bandage, it's important to clean the wound first to ensure it heals properly. Some bandages are also designed to absorb blood or other fluids, making them useful for more serious injuries. Overall, bandages play a crucial role in helping our bodies heal.
