    Okay. So why don’t we start moving on to the endocrine system. This is a really unique system that has wide ranging effects. Now, what are some of the components of an endocrine system? But first off is that it’s a collection of ductless glands which release hormones directly into the circulatory system. So it’s got this cascading effect, which is what sets it apart from some of the other systems that we’ve talked about so far. So the effects are slow to initiate, but they’re prolonged in their response and they activate distant targets lasting a long period of time. So as opposed to the quickness and the agility that was mentioned with our central nervous system and the peripheral nervous system and that we detect a sensory stimulus and we respond very quickly, the idea here is we don’t always need these superfast signals. Sometimes we need something that’s low and slow and this is exactly the system that does that. There are effects at several organs at the same time, there are things that can last for a long period of time, and the idea is the signals actually originated from the brain, but then they impact sort of the rest of your body. So, that ability to communicate throughout is really, really useful and necessary. So some of the endocrine glands that are important that you should know include, I’m just going to highlight some of them and we can’t go through all of them, but things like the pineal gland, the pituitary gland, the pancreas, the ovaries, testes, thyroid gland, we have the parathyroid gland, the hypothalamus, the GI tract, adrenal glands. So you can see it’s pretty expansive and there’s a lot of components involved and they’re all related. But we’re going to highlight...
