EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -What Are Scabs? As soon as you scrape or break the skin anywhere on your body, special blood cells called platelets (say: PLAYT-lits) spring into action: Platelets stick together like glue to make a clot. A clot is like a bandage over your cut that keeps more blood and other fluids from flowing out.

Detailed explanation-3: -Special blood cells called platelets form a clot at the injury. These cells act like a bandage to stop bleeding and keep out germs and debris. As the clot dries, it forms a scab. Your skin is healing its wound under the protection of the crusty scab.

Detailed explanation-4: -Forming the scab The clotted blood at the surface of the wound starts to dry out and forms a hardened scab. This may happen quickly, or take a few days. This scab forms a protective layer, while allowing cells to move around underneath it so they can continue repairing the skin.

Detailed explanation-5: -Serous fluid, also known as serous exudate, is a yellow, transparent liquid that aids the healing process by providing a moist, nourishing environment for the skin to repair.
