The outside of me
My skin is one of the organs of my body. Some waste products are carried
out of my body through my skin when I sweat. And my skin helps keep my
body at an even temperature.
All skin is tough, but some parts are tougher than others. The skin on
the bottoms of my feet is toughest of all.
Some of my skin is quite thick and some is quite thin. The thickest skin
is on my back. The thinnest skin is on my eyelids.
All skin, even the thinnest, is made up of two layers. The outer layer
is called the epidermis. The inner layer is called the dermis.
All skin, even the thinnest, contains tiny veins and arteries filled
with blood; nerves that help me feel heat, cold, or pain; and glands
that give out sweat and oil. Some parts of my skin also contain hair.
Hair grows out of little holes called follicles.
I can see my skin. But I can’t see all the things that are under it. I
can’t see the muscles and bones and nerves and the many organs that keep
my body working for me.
Since I can’t see these things, I’ll look at pictures of them.
