The Integumentary System

I'm hanging out with Micah at the Dermatologist to have a bump on his head looked at.

He makes a comment about how everything in the office has to do with skin. 

I reply, "well....it is a dermatology office."

To which he replies, " Yeah, but do they only deal with skin, or do they deal with the whole integumentary system?"

I had to admit, I wasn't able to answer that question unless he could tell me what the integumentary system consisted of.  

He could. And we determined that they DO deal with the whole system. 

And now I've proven that his schoolwork IS useful in the real world.
