How the Body Heals
Cuts and scrapes should be attended to immediately because of the risk of infection. Skin is the body's shield against germs. When a foreign body invades the skin, germs have an open invitation to raid healthy cells. Left untreated, cuts and scrapes can become painful sores, which are wounds that are slow to heal. Sores can also come from acute or chronic bacterial or fungal infections or from diseases that affect the body's ability to heal, such as diabetes or AIDS.
An amazing number of things happen when you cut or scrape yourself. When you disrupt the skin, a clear, antibody-containing fluid from the blood, called serum, leaks into the wound. The area around the cut or scrape becomes red, indicating that more blood is moving into the wound site, bringing with it nutrients and infection-fighting white blood cells. Nearby lymph nodes may swell. After a few days, pus (which contains dead white blood cells, dead bacteria, and other debris from the body's inflammatory response to infection) may form. And finally, a scab develops to protect the injury while it heals.
A scrape tends to hurt more than a cut because a scrape removes a larger area of skin and exposes a greater number of nerves. Scrapes often damage some blood vessels, so they are prone to bleed but usually not as heavily as cuts do.
