When the skin is injured, new cells repair and replace the damaged tissue. How do these new cells use nutrients during this process? Nutrients reinforce the cells' structure so that the injured area cannot be harmed again.

Nutrients help break down the cells so pieces of them can be placed over the injured area

Nutrients provide energy that the cells use to reproduce so that they can fix the injured area

Nutrients direct the cells from other parts of the body to the injured area to help prevent blood loss.
