**********How to study hormones.
The way that you study hormones is simple for every hormone there is a hormone that decreases it when there is too much of it in the body.

So in this corner you have PTH going up against calcitonin.
And in this corner you have insulin going up against glucagon.

Insulin breaks down sugars.
If you learn these hormones in pairs it is easy to see how the body wants to stay in homeostasis.
