Interesting things about your skin and the human body!

You’re sitting at home watching the television and up pops Jeopardy. You know, this question and answer show has been on forever. It’s still got the same cast of characters. So you settle back in your easy chair for the next 30 minutes to test your knowledge.

Up pop the categories one-by-one and there it is…..The Human Body.

The first contestant dives right in and goes for “The Human Body for $200”. And the answer is “the largest organ on the human body”. A deafening silence puts the audience on pins and needles and then someone buzzes in with the question…..

“What is the skin?”  Correct!

What’s the largest organ on the human body?

Your skin! Did you really know that?

But do most people really know your skin has many different jobs. Like it weighs between six to nine pounds and covers nearly two square yards of space. But that’s not all your skin has to offer.

How about this? Your skin is the number one line of defense in your sensation of hot and cold. There are millions of nerve endings in your skin that transmit data to your brain for you to decipher. Your sense of touch is all directly related to your skin.

Have you ever heard of bacteria and infection?

Your skin also has the job of providing protection against both of those bad boys. The skin acts as a thermostat for  body temperature. When you’re running a temperature or having flu like symptoms chances are something has gone a foul with your outer layer of protection, the skin.

It’s no wonder the skin care industry is so massive.  With all the different varieties of skin conditions people have there’s an endless opportunity for companies to provide skin care treatments as the solutions to those problems.

How about the Human Body for $150?

And the answer is “the outer most layer of the skin on the Human Body.”

And the answer is “what is the epidermis?”

Take a look down at your feet or hands. You’re looking at the epidermis. Remember those scrapes you got when falling off your bike. Chances are you injured the epidermis. It’s hard at work 24/7 even while we sleep. It continually regenerates new cells which make the long trip to the surface of your skin. This trip takes anywhere from two weeks to two months?

Have you ever wondered where the dead skin cells are? Take a look at your skin, it’s loaded with them.  When you shower or bath and wash your skin with the washcloth, you’re helping the new skin cells finish their journey by removing the dead skin cells from your body.  In skin care terms, you’ve just exfoliated your skin, although you may not really know it!

The epidermis is also the home to your sweat glands otherwise known as your pores. Did you know that we sweat all the time and that sweat exits through the pores?

Hey, let’s try “the Human Body for $100”.

The answer is “the layer directly under the Epidermis on the Human Body”.

The answer is “what is the dermis?”

Well, if you want to see your dermis, it could be a painful experience. You see, it’s the layer directly under the epidermis and contains all the nerve endings, blood vessels, oil glands, and sweat glands. The dermis also is home to two tough and stretchy guys called collagen and elastin.

So, if you really want to look at the dermis, you’re going to have to make an incision…not a good idea. But, it’s one we all experience in our lifetime. Your nerve endings will send you the message that the dermis is open for viewing. You may also see a bit of red fluid coming from it, otherwise referred to as your blood because you’ve cut yourself.

So now we know our sense of touch is related to the dermis. It’s the proud owner of tons of blood vessels. These blood vessels have two important jobs. First, they deliver oxygen and nutrients to the skin to keep it healthy. Second, they can also act as a garbage truck by hauling away waste.

Now, here’s a less painful way to check out the dermis. Pay a visit to grandma and grandpa and take a look at their skin. As we age, our skin gets a bit thinner and translucent so you can actually get a picture of the dermis from older people.

The dermis is also responsible for keeping your skin lubricated and moist because it houses the oil glands. The sebaceous glands manufacture the skin’s own oil which not only lubricates it but also keeps it from absorbing too much water.  The oil your skin produces is called sebum.

Any idea what the third layer of your skin is?

That would be the subcutaneous fat. It’s a protective layer of fat that acts as a shock absorber for the human body.  It also provides warmth to our bodies.

Makes you kind of wonder how much subcutaneous fat do bears have when they hibernate?

The subcutaneous fat is also the garden which sprouts your hair follicles. The roots are embedded in the subcutaneous fat and each hair follicle sprouts up right through the dermis and out the epidermis until its visible to the human eye.

Did you know some people have over 100,000 hair follicles on their heads alone?

What makes your hair shine?
