negative feedback.

In a Heating system the heater stays on till it gets hot enough that the thermostat turns it off. Then when it cools down the heater comes back on again.

In the hormone system. What ever gland produces hormones for a while till those hormones activate the other gland to produce different hormones which stop the first gland producing the hormone. Keeping it in a constant state of balance the same way a heating system keeps a house at a constant temperature.

I cant remember which hormones do what in which gland. But I'm sure you can find a flow chart of it if you google "negative feedback hormone regulation" or something like that.
