Which statement best describes skin cells' structure and function?
These cells are disc-shaped and flexible, which allows them to easily transmit and receive signals from all over the body.
These cells are flat and form overlapping layers to protect the body.
These cells are long and thin so they can contract and relax to move the body.
These cells are disc-shaped and flexible so they can easily travel through the body and transport oxygen.
