This title covers the ways in which we try to keep our bodies in a constant state. The scientific word for this constant state is homeostasis. By the end of this title, you will know how your body controls the removal of carbon dioxide, regulates your urine and checks you have enough sugar. It will also consider how the body looks after your temperature and makes sure no microbes infect you. Most of the mechanisms that this title describes occur by negative feedback. This means that if something the body is trying to control increases, it manages it by decreasing it. The process works the other way around as well. If levels are too low, the body will ensure that they increase again. This title also explains how both the nerves and hormones help with these processes.
