After my research lesson in science today i decided to do a little more reaserch on the excretory system.
The information i found was very useful and was very informative.
I also have been writing notes throughout every science research lesson and when i am researching by my self at home.
Why do we need it? - The Excretory system is a way of the body to release toxin. The excretory system is a biological system that removes excess, unnecessary or dangerous materials from an organism. It is responsible for the elimination of oxygen waste products of metabolism as well as other nitrogenous materials.
