How does your skin protect you

The skin acts as a natural barrier between the outside environment and our body in both the macro and micro world.

Explanation:

The skin protects our organs and tissues from the outside environment, preventing other organisms like bacteria from stealing our body's nutrients and harming our body's cells. It also protects us in the event that our body is hit with something (for example, a fall).

Your skin protects you by having the immune system.

Explanation:

Your skin produces the covering of cells, and has an immune system that protects you from becoming ill.
