The excretory system is a system that connects to the digestive system. It starts at the mouth and continues down the esophagus, after that it travels down to the large chamber of the liver and stomach. It travels past the pancreas and the gall bladder. You swiftly follow the path of the small intestine and finally goes to the large intestine and finally to the rectum. The kidneys, main organs are filters. There are two of them located near the spine in the middle of the back. The main organs of the excretory system are the bladder, kidneys, lungs, liver and skin.

The excretory system is like the sewage system because the excretory system gets rid of waste that the body does not need. The body also gets rid of natural gasses which can be fatal if not released from the body.
