The Heaviest Organ

Well, I take the PA National Certifying Exam (PANCE) tomorrow, so of course I've been studying as much as possible. I think I will do alright on the exam, but I am still nervous about it. For one reason, the stakes are high--if I don't pass, that would be very bad--and it's a 6-hour exam, covering all branches of medicine.

While studying today, I ran across a statement that is provided as an introduction for almost every dermatology text I've read:

"The skin is the largest and heaviest organ of the body"

Yuck! Does anybody else imagine a pile of human skin on the floor?
Why does every author discussing dermatology feel the need to repeat this useless, disgusting piece of information? I can't think of a way this factoid is medically helpful. Every time I read it, I shudder and try not to think of Silence of the Lambs. For those interested in the specifics: the skin weighs about 9 lbs and has a surface area of 20 square feet. Gross.

Wish me luck on the PANCE tomorrow!
