Like I said earlier, the major
function of this system is to rid the body of harmful substances. It
does through the wastes of urine, feces, carbon dioxide and sweat. If
we did not have an excretory system, we would be immediately poisoned
after eating. Also, since it works with other systems, it helps them
functions as well. It allows waste to safely leave the body without
harm. If it couldn't, it would build up in your body and kill you. Like
I said, its main function is to rid the body of harmful wastes.
