The conditions in our body are carefully controlled by hormones, to ensure that

everything is constant and our body functions efficiently.


There are several aspects of our body that need to be controlled. Body

temperature needs to be controlled to ensure that the enzymes can work



Blood sugar levels need to be controlled to ensure the brain has the correct

levels of glucose


Water content also needs to controlled to ensure our cells have the correct

amount of water. Too much water can cause cells to burst and too little will

cause cells to shrink.


Hormones use a system called negative feedback, which allows them to

maintain the conditions at just the right level.




One of the main hormones in the body is insulin. Glucose levels are regulated

in the body by insulin which ensures that the levels do not get too high or too

low. Insulin is produced by the pancreas.
