Our system is the excretory system. The purpose of the system is to get rid of materials that the body doesn’t need anymore. It’s essential to do this because otherwise waste would get blocked up and eventually poison you. You will hear about how waste is gotten rid of by the body in this report.

For solid waste, you need to have waste products which could include undigested food, water, salt, skin cells, bacteria, bacterial waste and pigment. All these things come together and, as they go through the small intestine, these things get filtered from the things you need to live on. The waste products get pushed on to the large intestine and then exit the body. The brown color comes from bacteria breaking down other bacteria. Some diseases you could get in this system are diarrhea and the intestinal flu.

For liquid waste, blood goes through the kidneys and the kidneys filter out any waste products which is mostly extra water (99.8%), salts and urea. Liquid waste is made by the kidneys filtering blood and taking out any waste products. When the kidneys filter this, it filters down into the bladder which fills up like a balloon. Then nerves inside the bladder tell your brain that you better go pee right away. Your brain usually says, “no, don’t bother me now.” This delaying can go on for a little while, but then you will really need to go and you better find a place quick. Liquid waste is cleaner than the skin on your face and the spit in your mouth. That’s because it is not home to bacteria. Diseases you can get from liquid waste are . What this disease does is make your kidneys stop filtering blood and that will eventually kill you if you don’t get it treated. Another thing that can go wrong is if you have some kind of accident where one of your kidneys gets destroyed. In that case the other kidney gets bigger to accommodate that.
