Hank begins teaching you about your endocrine system by explaining how it uses glands to produce hormones. These hormones are either amino-acid based and water soluble, or steroidal and lipid-soluble, and may target many types of cells or just turn on specific ones. He will also touch on hormone cascades, and how the HPA axis effects your stress response.

I've invited you all here today because I wanted to talk to you about some ugly stereotypes they're going around I've been hearing a lot of unfair on the scene Lee and unscientific generalization to be made lately mostly have to do with  and your hormones set of behaviors and conditions most of which have to do with reproduction or sexual development or accident clue what my brother John is referred to as a skoodilypooping and is being all moody or white tried watching a commercial for car insurance which not even close but I just mention what they really mean is hormones 50 different types of this very minute but only a very few of them have anything at Hollywood  the truth is from birth to death every cell in your body is under your hormones influence response to stress in general and Incredibly in overall homeostasis that keeps you not dead. Hormones are just there to make other hormones trigger even more hormones and these hormones run through your body no matter what it is whether you have Zips to the reality is we are all hormonal all the time I'll get to begin to understand our hormones and the endocrine system that produces releases and reabsorbed we have to step back and take a broad view also by looking at how your horn interact with your other organ systems in your body has two bosses 2 complementary systems that are constantly shouting instructions over each other to all your bits and pieces sold your endocrine system and your nervous system are constantly traffic information around your Corpus Intel making demands controlling your every move they just have totally different ways of doing it your nervous system fuses lightning-fast of action potentials delivered by an expressway made of neurons to specific cells in organ such an endocrine system prefers lower it secretes hormones not through neuron so they move more slowly now compared to your heart or brain or other are you'll be more glamorous Oregon's your endocrine systems organs and glands are kind of small and lumpy instead of being all nestled together like in your other organ systems these guys are scattered all over the reindeer throw to your kidneys to your any structure that makes and secretes a hormone and the master gland in your body is the pituitary hormones that signal to make their own hormones the endocrine system also includes do organs like the gonads the pancreas and the placenta and pregnant women have some other non-hormonal functions and are made up of multiple tissue types since in addition to all of it. produce and release hormones still thanks to all these glands and organs you got these hormones diffusing through your blood doing all sorts of different things but the thing to remember about them is that a hormone can only trigger a reaction in specific cells their so-called target cells that have the receptors for it so just like some keys can open many locks While others only work with one in the hormone Target sell relationship either be widespread or localized thyroid at the bottom of your throat produces the hormone thyroxine which stimulates metabolism in bonds receptors in most of the cells in your body and it only target specific cells in the ovaries and testes how do hormones bind to their target cells because of hormones chemical structure determines if its water like most Amino acid-based ones are lipid soluble steroids are kind of hormones have receptors on the outside of their men lipid soluble hormones on the other hand can just basically gliderite through that cell membranes increasing or decreasing some of its functions maintaining your body's homeostasis in one way or another so if anybody in Balance rhubarb pie and just make things interesting let's say they're all a mode your blood glucose level is going to go through the roof and the pancreas regulates your blood sugar by releasing two different hormones insulin and glucagon lower your blood sugar by increasing the rate at your cells store the sugar either is glycogen or is fat for later use alpha cells in the pancreas will instead which helps raise your blood sugar levels in part by decreasing the storage of sugar in your cells during the release of glucose can be the result of either hyper too much or hyper go to little secretion of certain hormones which throw your homeostasis off balance there lots of more common in less obvious ways your hormones can get out of bed because of some disorder because these things when chemicals are just caught up in a chain reaction which contain wildest some side control other hormones which in turn control steel nor hormone given moment put one of the big ones when it's really worth standing is the hypothalamic-pituitary-adrenal Axis or the HPA axis because you don't want to have to say that every time this is a complex series of interactions between these daily processes like digestion sexuality you response and how you handle stress because of all the glands involved endocrine system coordinate that everybody keeps talking about the endocrine systems companion for the sympathetic nervous system in times of high stress does things like speed up your heart rate and blood away from the stress response are carried out by your endocrine system nervous and endocrine systems that work together in times of Crisis is where the hypothalamus comes in a Starfighter flight scene from a few lessons ago burning house scenario play sleeping your dreaming about petting pandas with Emma Watson or whatever when the smoke alarm goes off in your brain triggers the RH or corticotropin-releasing hormone it makes me very short trip through the bloodstream to the anterior pituitary gland or ACTH again bloodstream to the adrenal cortex of the adrenal glands on top of your kidneys corticoid and mineralocorticoid hormones Publix deal with data de-stress by keeping our blood sugar and blood pressure balanced like wake me up in a burning building stress your blood pressure dumping glucose into your bloodstream shutting non emergency services like your immune system and sperm and egg development has been stopped secreting crh which actually causes the other glands to stop secreting their Panic hormones as those stress hormones linger in the blood before being broken down enzymes from teenage crushes owner of hormones I hope you'll join me in and give them the respect they rightly deserve we look at the endocrine system and how it uses glands to produce hormones these hormones are specific ones we also touchdown hormone Cascades PA access affects your stress response thank you to our Headmaster of learning,
