What part of the cell theory explains why your skin is able to repair itself after being cut

Answer 1

Cells are created from existing cells is the part of the cell theory which explains why the skin is able to repair itself. The body produces 300 million new cells every day. After getting a cut or scratch, the skin may start bleeding. This happens when the injury tears down the tiny blood vessels that is found under the skin’s surface. The body wants to stop the bleeding so the platelets will come to the rescue.

At the cut, platelets stick together. This is how the blood clots which then become a scab. This protects the area so the cells underneath it can have the time to heal. Beneath the scab, new skin cells multiply to repair the wound. Damaged blood vessels are restored and blood cells end the infection in the wound. And also, under the scab, a new skin layer is formed.
