Describe the ways in which each of the following body parts excretes waste from your body. lungs skin intestine liver urinary system

Lungs- when we exhale we get rid of c02 that is in our system.
Skin- you see, when you get into an intense workout you start sweating right? What some might not know about that sweat is that it contains salt. So when we have too much salt in our body and we sweat it helps get rid of some of that excess salt that we don't need.
Liver- the liver is a little more complicated. But what it does is helps pass the liquids we drink into our urinary tract.
And of course the final thing you bring up. The urinary system. It helps by urinating the water or juice or milk etc you just had so you don't leave it in your system. Because the longer it is left in there the more bacteria will build up and then you can get a nasty infection.

Ok, before buying a burger. think of you diet and calories. how many calories are you suppose to eat a day. and look at how much fat, calories, salt is in it. if it is ok to you, then buy it. but if you think that it's to much fat and salt for you. don't buy !
