How the body works

Today in 8Rc we went on to a web site called Kidshealth.org make sure to click on for kids.

So one of the videos that I watched was about the hair.

I found out that you grow hair almost everywhere on the human body.

You lose 50 to 100 hairs a day. 
Another thing I watched was all about your bladder.
Your bladder is a little sack that holds your pee.
Your bladder expands when it gets to full
and your bladder decreases when you are peeing.
