Always a part of you

Most living things are made up of one or more cells. These are more cells from our bodies and from plants.

Skin 2

I have some skin on the side of one of my fingers that has been very damaged from the sun, and it is hard and flaky. This is a piece I pulled off and put into the electron microscope. You can see the outlines of the dead, keratinized skin cells, and also a hair pore. The structure of skin is designed to prevent loss of body fluids and protect the body against the environment, and microorganisms and toxic chemicals that might be in it. Microorganisms are repelled by the dryness of the outer skin (like this piece), by the fatty acids in the oils on your skin, and by the lactic acid in sweat.

This is magnified about 220 times.
