What is your largest organ? While this question is a classic "Sunday school" joke that you could ask anywhere, it is also a great way to find out how much someone knows about their body. The largest organ on the human body isn't the brain or the heart and it most certainly is not whatever answer your mind finds when its in the gutter. The largest organ of the human body is the skin.
SKIN: As your largest organ, skin is your first line of defense against injury, illness and (dis)ease.
