Endocrine System, Part 1 - Glands & Hormones: Crash Course Anatomy & Physiology #23

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 affects your stress response.

I can't get over how cute the little glands have been animated to look.

[kaitlynndixon]

I watch these when I was in A&P 1 and 2 my freshman year of college, and now I’m watching them all again in nursing school and I’m about to graduate with my BSN! I am SO thankful for crash course 😍

[cortster]

That one piece of hair sticking up... Noticed it half way through the video, and now I can't unsee.

[IloveSPIDERZ]

Is anybody else watching this the night before you're getting tested on this? lol

[maurdie]

No, I'm watching it the night before I need to teach it!

[cassidylastname]

My biology grade went from an 83 to almost a 90 in two months after I started using crash course to study. Thank you so much for these videos

[sarahswayze]

These videos are a LIFESAVER. I don't know how I would have gotten through A&P without them!

[RMSammy]

God this was probably the hardest chapter that we learned in AP Anatomy & Phisiology. This and the Nervous System...

[lindsayhuggins]

This made learning the endocrine system so much better than just some teacher reading slides!!!

[fritzlandaandre]

Bout to take this exam in 2 hours !! I think I ready✊✊✌
Edited: OMG🤣 thank you so much crashcourse😘😘😘, I got a 97% on my🤗🤗 biology 2 ezam

“That keeps you not dead”. You’re so cute. I love your classes

[loveshelby]

When you learn more from a 10 minute YouTube video than you do from your college A&P professor :(

[valery]

Bless this video, because we have been talking about hormones in my advanced physiology class for like a month, and this solidified a lot of the foundation of what the professor has been talking and now things make more sense!! Thank youuuu, Crash Course!!

You should make a study guide/ note sheets! I want to thank you, I watched most of your videos when I was in A&P 1 and 2. I did well in both and I am now in my second semester of nursing.

[laur]

i watched this 2 years ago in the 9th grade and tbh i wasn’t understanding this as well as i am now, i’m happy i made improvements.

feels good to understand what he’s saying now bc i’m smarter lool

[katederepasmusic]

Whenever I don't understand anything at uni I stop everything and crash course it. You are a life saver!

[NatasshjaSoncini]

This is incredible, the last time I heard someone explaining how the hormones work was when my doctor told me I had two little tumours in my pituitary gland and all the trouble they're causing! Anyways, this video is brilliant, thank you so much.

[waltermcmain]

Petting pandas with Emma Watson sounds so relaxing.

[k-beautytv]

We just started the Endocrine system chapter in my Intro to A&P class.. I’m making sure to study every night and watch these videos to make a 100 on the exam haha
