It's a shame that I learn more watching these well produced videos than I do in my college courses. I wish my professors had as much enthusiasm as the host of these videos. Regardless, well done. Subscribed and will donate via patreon!
I'm lucky enough to have a professor who recommends these videos. She is extremely enthusiastic about her job and it makes learning the material so much more enjoyable!!!
I can understand how it might be harder to sound upbeat for every class every semester teaching the same subject for like 20 years. He just has to go over this content like once.
This channel is absolutely AMAZING ! Every time I am introduced to an Anatomy concept in class I go on here the day after and take extra notes. This is usually when I get my 'AHA' moments and things come together. I recommend you to all of my friends ! Thank you for the free help, you have no idea how much I appreciate it !
Dear CrashCourse, thank you so so so much. I have just been accepted to study biology, my biggest passion, in the University of Helsinki, and in some ways it's thanks to you. This year there was an entrance exam of five essays and one of them was about nefrons and how the body regulates their functioning and I believe that mostly because i had just watched your videos about kidneys and hormones and the nervous system, I freaking aced it. I hope that you see this and can feel my enermous gratitude for helping me get in to university so that in a few years I can become a researcher and save the planet. I'll thank you again in my Nobel victory speech.
Been watching CrashCourse videos since my pre-med days. As soon as I finish med school and start earning, I will make sure to donate to the hardworking people behind these miracle videos. I LOVE CRASHCOURSE!! P.S. I just got a hold of your book, Hank! Can't wait to read it!
As someone with Grave's Disease, I learned more about my own illness here, at CrashCourse, than I ever did at my endocrinologist's office. Thanks CrachCourse!
As someone who has been living with thyroid crap for ten years (mostly underactive, sometimes overactive) this video is refreshing. Hopefully it will help someone else.
I had Graves and was able to bring my thyroid levels down to normal through dietary changes. It took 4 months to bring the numbers down and one year to bring them to normal. Now, I do periodic testing.
These videos have helped me more than any anatomy class. In fact, my professors usually attach these videos. It's almost like they're like "i know what I said makes zero sense. Go listen to this guy while I collect my check"

Yay! So glad to be mentioned as a supporter of a video featuring one my favorite organ systems: the endocrine system! (especially the thyroid!) Keep it up, CrashCourse!
Hey guys, this is the first time I have ever commented on anything on RUclips. I even went to making a channel just so i could express my views with you. I'm a single mum of 3 and doing my first year of nursing at university here in Australia. When it has come to A&P, I have found your videos to be extremely helpful in my grasping of the major concepts. You have made my study life ALOT easier and I have just received a high distinction grade. I want to thankyou for that, as without these videos I would have been lost. I can't afford to support you financially at the moment but my gratitude is above and beyond. Please keep up the great work you guys are doing!! Many thanks!!
You and your brother have saved me, thank you. Even after reading and attending lectures, more often than not this makes a thousand times more sense. So thank you for making AP classes in highschool more bearable and College easier to understand.. and fun :)
Even though I have finished all my revision for my exam tomorrow I'm finding myself putting on the playlist in the background as I do things so I here someone else tell me what I know. So glad these are here
Wow, I really have to say a big thank you! I wish I would have found your anatomy and physiology playlist 10 weeks ago when I began my anatomy class. I have fallen behind and have been trying to find a good outside source to help guide me and recap what I should know. I found these endocrine system videos, since it's apart of my unit exam in a week, and am utterly shocked at how helpful these are. I am going to go back and watch them all for this subject. Thank you all for your hard work! Glad it is finally clicking, wouldn't be there without the amazing Crash Course team! :) xoxo!
I was diagnosed with hyperthyroidism when I was about 10. When I was 14 I was rediagnosed with hypothyroidism and it has remained that way for the past few years.
Amarís Blackscale So what are the symptoms of hypothyroidism? The opposite to the symptoms presented in the video? Like tiredness and exhaustion? I'm asking because I have some of those symptoms all the time and they really restrict me in everyday life.
Life without the boring parts Hypothyroidism has the exact opposite symptoms of hyperthyroidism, because basically, your body's metabolism is slowing down, and _down_, and *_down_*. You're also probably sensitive to cold and have abnormal weight gain, as well as several other such as dry skin, stiff muscles and a weak heart at this point if you do have hypothyroidism. Though remember that's not the _only_ cause, probably you're just chronically fatigued. Hypothyroidism causes unexplained tiredness even when you're mostly not doing anything.
Thank you so much for this video. I had thyroid cancer and my whole thyroid removed. Now I have surgical induced hypoparathyroid. I like being an informed patient so I can feel confident about my care, especially after by botched surgery.
It's nice to see a video from people you respect about a disease you have. It's very validating when sometimes having a hidden illness makes you feel like you're just making it up even though you know otherwise. Thank you Hank. ☺️
I am the same way! I love learning especially when science is involved. I just finished my bachelors in biochemistry back in May. And come January I am going back to school to become an RN. My fiancé just started college a few months ago for botany and was really struggling until he found these videos!
yeah the 'haven't even been diagnosed yet' deal is no joke, i spent 4 years with rampantly out of control undiagnosed graves' (when i finally got tested my t3 and t4 were literally off the charts and could not actually be measured). if something seems wonky get it checked the frick out.
I'm not in college but I love anatomy so I've binged watched almost all of these videos. I actually have Hashimoto's Thyrioditis and its not fun. Joints hurt, not much energy, dry skin, constipation, and anxiety. I'm only 21 but I feel like my body is 50.
+razzar508 I can relate, i was diagnosed with fibromyalgia and eventually hashis...I was in school for A&P when i had major a ha moment! I started to study to be a nutritional therapist, and it unlocked the doors to my health. I recommend you investigate that path. It saved my life. I now help others! You don't have to have these symptoms prevail~and Im for fuckin real! I am more than willing to give you more info...hmu razzar bsweeterman@gmail Bsweet
Thank you for your amazing explanatory videoes. At the middle of the video, you said mistakenly HTP AXIS, it is not that big deal, but to avoid it in the upcoming videos. Best wishes
Would've loved to see this from the perspective of/with an example via adrenal dysfunction and the all-too-common adrenal fatigue (like in "nervous breakdown"). Just for personal interest since those with anxiety disorders and ptsd often end up with so much distress here. Loving this series.
I was born without a Thyroid Gland (so have hypothyroidism) and you've just taught me more about what the thyroid does more than my doctors ever have 😂
I have watched your videos since the beginning of biology 110. You helped me so much in that class and I've watched all the anatomy and physiology videos up until this one for my anatomy class this semester. You are such a big help! Thank you for sharing your knowledge!
I absolutely love these video's. I use them as an accessory to my studies to enforce my understanding of the material. They've been done so well that it doesn't even feel like studying anymore, it's just relaxing and a shitload of fun! And if some days I don't feel like delving straight into theoretical text books, a few of these video's is enough to trigger my motivation to get back to it. Thanks! When I'm taking my exams in a while, I'll be very gratefull that I've found these, and I'll probably continue to watch them after to keep this knowledge fresh in my brain.
I had a small carcinoma in my thyroid, and had it(entire thyroid) removed about 10 years ago, I take 2 small pills daily to replace the hormone it produces.
Amazing videos overall! I can now use this video to share what graves disease is with friends, family clients so they can have a better understanding of the body and thyroid disease! Thank you. Keep up the amazing work!
+Priya Edwin No, hyper-thyroidism is too much activity in the thyroid. Hypo-thyroidism, in +feitocomfruta's case, is too little activity in the thyroid.
I have Kallmann syndrome, which causes a malfunction in the HPG axis (hypothalamus - pituitary - gonadal). The hypothalamus fails to release its hormone (GnRH) which prevents the pituitary from releasing the hormones FSH and LH which prevents puberty from occur and prevents the testes or ovaries working correctly.
A minor correction: Glucose component parts are not used to produce ATP. Instead, the energy released by breaking down glucose is used to form ATP (from ADP and inorganic phosphate). The glucose components (together with some oxygen) instead end up in carbon dioxide and water. Or if you are out of breath; in lactic acid.
I have hypothyroidism, been taking medication and getting my blood drawn since I was a few days old, and the type I have is what I like to call the “where’s Waldo” thyroidism. Basically mine is not where it’s supposed to be, it works but because it’s not where it’s supposed to be I have to take medication.
Good luck to everyone here cramming before their test.
thank you
I’m here because I love the this series
Thank you kind sir.
thanks i would probably fail without this vid
why are all the organs in these videos so adorable, and when can i get a plushy version?
jtsurge try www.giantmicrobes.com/ :)
I want the thyroid gland with evil eyes!
jtsurge iheartguts.com/ !!
ofravensandashes I just want two of those eyes so I can scare the squat out of an unexpected person entering my room.
Angel Van Dam ME TOO. I'd put it down as "highly unlikely" to ever exist, but I would love it dearly if it did.

I LOVE THESE ANIMATIONS SO MUCH
This is my first year of medical school. This channel is helping me a lot more than I thought.
How's school going so far?
Tarik Husein did u make it?
Please do a crash courses series on Microbiology.
Crash course has saved my life my throughout my college years. Definitely will contribute and make a donation for all their help!
ikr! can't wait to start earning money so i can make donations :D

Finally, I can understand what my A&P textbook has been trying to tell me! Thank you Hank, you've done it again 👍
10 minutes video? Spending 1h to 2h to write a proper mind map of the videos... such good course!
This channel actually makes me want to learn

Endocrine system: “Wow what a great day to produce hormones!”
Immune system: “I don’t think we can keep fighting this virus chief”
Have my 200 question final in 2 hours. Wish me luck.
Same!! Hope all went well!
mistdust Made an A!! It was so freaking mentally exhausting though. Good luck!
200!!!!!!!!!!!!!!!!!!!!!!!!!!
Dude wtf 200? For what class?
How'd it go?
The pituitary gland was so CUTEEEEE
i have a test on this tomorrow :D
JD96893 I hope it goes well! (Or went well, as this comment is from yesterday.)
-Nicole
+JD96893 How'd it go?
i take finals on this tomorrow. video binging ftw
I have a test on the whole endocrine system with all 8 hormones from the pituitary gland and thyroid hormones
JD96893 I have a test on this next class
I'm a first year student in med school and due this quarantine I'm studying online. Your videos make learning a lot easier! :)
Wow, you guys are all amazing! I've been stressed about my A&P 2 course this semester but you guys have really helped! Thanks for all you do!
As someone with Hashimoto's Disease, I'm really feeling this episode.
and I, with grave's!
I love how you make A&P so entertaining! the texting glands made me giggle :)
I love this channel...
Don't we all...

That woman losing her jacket makes me sad
Don't worry you're just hormonal.
all the time.
The best overview for basic biology courses I've ever seen. Thank you.
Your energy makes this fun and more interesting to learn! How do you consistently talk so fast though? Haha.
You and your brother have saved me, thank you. Even after reading and attending lectures, more often than not this makes a thousand times more sense. So thank you for making AP classes in highschool more bearable and College easier to understand.. and fun :)
If you were my biology professor, I wouldn't need to study so much lol.
IKR!
really I will bring A* always
Even though I have finished all my revision for my exam tomorrow I'm finding myself putting on the playlist in the background as I do things so I here someone else tell me what I know. So glad these are here

a bit too much

Though remember that's not the _only_ cause, probably you're just chronically fatigued. Hypothyroidism causes unexplained tiredness even when you're mostly not doing anything.
Amarís Blackscale Are you taking Levothyroxine sodium now?
You may have Hashimoto's thyroiditis since it can start with hyper and go to hypo. I have it!
seriously, my favorite study tool for a&p. Thank you for somehow making me laugh through out the endless hours of studying!
The thyroid gland even looks cuter after it has gotten angry
Thank you so much for this video. I had thyroid cancer and my whole thyroid removed. Now I have surgical induced hypoparathyroid. I like being an informed patient so I can feel confident about my care, especially after by botched surgery.
You know what's so awesome about you guys? You almost perfectly line up your video subjects with my chapters in A&P! Thank you!
Crash course always puts me in a better mood like everything is going to be okay🤗
This guy makes learning about anatomy and physiology so fun! Thanks crash course!
I am in Pre-Nursing A&P 2 and I have my first test on this tomorrow! These videos are awesome!
literally exactly same situation!
We need to get Hank a new jacket that fits him properly.
"homeostasis is life" I shall write this on twitter and hope my friends think I'm smart xD
i have Hypothyroidism and I learned a lot from this.Thanks!
Great vids on the endocrine system! Any chance you'll make more?
Will there be an episode about different thyroid diseases?
Bless this video. Now I can use this to somewhat explain to people about thyroid diseases.
It's nice to see a video from people you respect about a disease you have. It's very validating when sometimes having a hidden illness makes you feel like you're just making it up even though you know otherwise. Thank you Hank. ☺️
Studying Naturopathy. This channel is going to be so helpful on my journey, learning about the anatomy and physiology. Thank you
I'm such a nerd. I watch these because I find learning entertaining. I'd choose Crash Course over Netflix any day.
I am the same way! I love learning especially when science is involved. I just finished my bachelors in biochemistry back in May. And come January I am going back to school to become an RN. My fiancé just started college a few months ago for botany and was really struggling until he found these videos!

I was cramming for my A&P II midterm and this video helped me pass. Thanks, guys.

i had other things to do the past 3 days.
i have a test tomorrow.
i need this.
These videos make it so much easier to read hours and hours of blabbering Guyton and Hall. Thank you Crash Course! :)
I'm a thyroid cancer survivor, so I'm familiar with hypothyroidism.
+feitocomfruta Congratulations for surviving !! Is hypothyroidism a type of cancer?? I'm curious.
+Gemma Hipkin Hypothyroidism is a symptom of thyroid cancer, but can also be caused by other things. It's simply an under active thyroid.
+feitocomfruta me too!! haha
feitocomfruta correct me if I am wrong but isn't it hyperthyroidism? And BTW I really admire your strength!!!😊
+Priya Edwin No, hyper-thyroidism is too much activity in the thyroid. Hypo-thyroidism, in +feitocomfruta's case, is too little activity in the thyroid.
I have been using your anatomy and physiology videos as a way to study and they have been so helpful and informative. Thank you so much. :)
this channel is helping em so much in college rn
I have Kallmann syndrome, which causes a malfunction in the HPG axis (hypothalamus - pituitary - gonadal).
The hypothalamus fails to release its hormone (GnRH) which prevents the pituitary from releasing the hormones FSH and LH which prevents puberty from occur and prevents the testes or ovaries working correctly.
When you learn more about your Graves' Disease from Hank than you do from your endocrinologist. Thank you Crash Course!
Hats off to the graphics team, and everybody else
evolution is pretty damn amazing
im very thankful for this channel i have a test on monday and ill be watching these videos daily!
Your videos are sooooo great! I'm telling all my friends about it. It's the best way to really learn!
HUGE THANK YOU for all the amazing videos and animations. Getting ready for my exams now and it's a huge help having you!❤💐❤
A minor correction: Glucose component parts are not used to produce ATP. Instead, the energy released by breaking down glucose is used to form ATP (from ADP and inorganic phosphate). The glucose components (together with some oxygen) instead end up in carbon dioxide and water. Or if you are out of breath; in lactic acid.
I LOVE CRASH COURSE!!!! It's saving me!!
Please! MOAR! This is so interesting to me!
I learned about it today and it should be the easyist systems ever!
Have a test on this tommorrow!... Thank you Crash course
These videos are blessing my grades
Such amazing complexity. We are indeed wonderfully made.
ik a lot of people don't like him talking fast, but it actually helps my monkey mind focus lol
Man, you should have made this videa before my final exams of the years ! :D
I have hypothyroidism, been taking medication and getting my blood drawn since I was a few days old, and the type I have is what I like to call the “where’s Waldo” thyroidism. Basically mine is not where it’s supposed to be, it works but because it’s not where it’s supposed to be I have to take medication.
Man I love CrashCourse Biology! ! ♥
the text message notification sounds lol
I have to say how beneficial this website has been to me! I have a final and this has really helped me! thank you :)
This channel is THE BEST.
Now, with this video, I have become your fan :)
Cheers to you for such a superb channel.
Keep up the great work !
you really teach very very well than our college professor ...............
