How does the human body heal wounds?
When we get a wound, our blood clots, then new skin cells grow to close it up.
When you get cut, the bleeding stops first. Tiny bits in your blood stick together and make a plug. This is called a clot. The clot dries up and forms a scab. The scab keeps germs away from the wound underneath.
Under the scab, the body's tiny soldiers called white blood cells get to work. They catch germs and destroy them. At the same time, new skin cells start to grow and slowly fill up the wound.
After a few days or weeks, the new skin is fully formed and the scab falls off by itself. Underneath is smooth, fresh skin. Sometimes a small scar is left, but it fades over time too.
Our body does this all the time, without us even noticing. That is why it is important to keep a wound clean, so it heals faster.
