The excretory system is basically the system that deals with what the body releases. That doesn't just mean "poo" and "pee." It can also mean sweat. But what this system does for animals is that it basically gets rid of wastes and toxins. Without this system, all animals would probably die from poison and stuff like that. Humans throw up. That's also a part of the excretory system (I think), because vomiting gets rid of stuff the body considers dangerous.
