What's the largest organ in the human body? I think it's the skin but my friend - it's the liver. Can you settle our dispute please?
I'm pleased to tell you that you're right and your friend is wrong. The skin is actually classed as an organ as it performs a function in its own right and has specialised tissues to do it. I hope for your friend's sake that there wasn't too much riding on the bet!
