If you get a small cut, you may clean and cover it with a bandage, and move on with your life. Yet under that bandage or in the open air , the body orchestrates a complex cascade of events designed to heal wounds big and small. Stopping the bleeding hemostasis. When your skin is cut, scraped, or punctured, you usually start to bleed. Within minutes or even seconds, blood cells start to clump together and clot, protecting the wound and preventing further blood loss.
These clots, which turn into scabs as they dry, are created by a type of blood cell called a platelet. The clot also contains a protein called fibrin, which forms a net to hold the clot in place. Once the wound is closed with a clot, the blood vessels can open a bit to allow fresh nutrients and oxygen into the wound for healing.
Blood-borne oxygen is essential for healing. The right balance of oxygen is also important — too much or too little and the wound won't heal correctly. Another type of blood cell, a white blood cell called a macrophage, takes on the role of wound protector. This cell fights infection and oversees the repair process. Customer Rights Customer Rights.

You might see some clear fluid on or around the cut at this time. That is helping clean out the wound. Macrophages also produce chemical messengers, called growth factors, which help repair the wound.
Blood cells, including oxygen-rich red blood cells, arrive to help build new tissue. Chemical signals tell the cells to create collagen. It serves as a type of scaffolding. Occasionally, you see the result of this process as a scar that starts out red and eventually dulls. Over time, the new tissue gets stronger. You might notice stretching, itching, and even puckering of the wound as that happens.
The wound gains strength quickly over the first 6 weeks of healing. Depending on the size and the severity of the wound, the entire healing process might take up to a couple of years to complete.
The process seems simple enough, but wound healing is really quite complicated and involves a long series of chemical signals.
