Excretory System

By: Jimeria Webb & Dejanae Smith

What does our body do with waste? What is it called and what does it do?

The Excretory System is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. The Excretory System is responsible for the elimination of wastes produced by homeostasis. As our bodies do everything it can to survive it produces wastes. The wastes we carry are chemicals that are toxic and can hurt and very much kill you. As our cells break down amino acids they are also producing a toxin called urea. The cells will then excrete this urea into your blood. As the blood travels through your body they get more and more of wastes and then enters an organ called the kidneys. When the blood enters your kidneys it is now cleansed. Your kidneys remove the urea from your blood and carries the urea down to your bladder to form urine. Slowly the bladder starts building up more and more urine the kidneys are giving to your bladder. As soon as it gets full the sensation of it will then tell your brain that you have to remove it and then its all gone.
