i tried but youtube needs a sliding scale playback manipulator and i would put it on like 95 so it wouldnt sound choppy. all though i will admit i like the speed most times...you can get into a serious groove but you have to listen to it multiple times but they intend for them to be replayed and paused. the issue is the youtube playback thing i wish they would make it like MX player but im sure it would be more difficult or they would have used that type of system first.
If I could, I'd give this a million likes. I can't like it enough. A single "like" is terribly insufficient. This video will be incredibly helpful to my students when we cover diabetic medications and cholesterol drugs (which of course, are only used when diet and exercise aren't enough). Based on the responses I see here in the comments, it's clear that many people have had experience with diabetes-related and nutritional issues. But that would be an entirely different CC series... I don't suppose there are any diabetologists or registered dieticians out there who want to work on that series? :-)
I love these CC sessions. The host/professor has such a loving sense of humour! It is key to making any theme available to people who´d be the leeeast interested in any given subject. He could entertain every single class because of his teaching fashion :) It´s always a pleasure to watch these vidoes. Apart from being fun and entertaining, they´re informative!!
I LOVE YOU! PLEASE MAKE MEDICATION PHYSIOLOGY VIDEOS!!!! I watched your videos during all my bio corequisite classes which helped me get into nursing school!! Thank you so much.
No words describes how thankful I am for watching you. Thank you so so so much I been reading my book for 3 days already and finally I understand how it’s working after watching this 10 min video Thank you !!!!!
Great video. Understanding how your body handles food can go a long way in helping to make healthier choices in a way that nagging just doesn't do. I remember eating donuts and a Pepsi for lunch every day in middle school. I wasn't overweight, so I didn't see any reason to change. After I learned what was going on in my body when I ate, and the reasons eating a healthier diet was important (and the consequences of not doing so), it actually made me stop and think every time I ate. Years of nagging from my parents couldn't have gotten through to me like this kind of knowledge. Decades later, I still think about it when planning meals.
Watching both metabolism and nutrition crash courses repeatedly because my ap2 instructor “ran out of time” and completely skipped the chapter but still wants us to understand everything for the exam coming up 🙃
It's nice to see that someone can make learning interesting for children. My little brother enjoys your videos and it helps him learn and elevate to a higher academic level, (BTW he's in high school). Remember to keep up the good work man.
Thank you for giving such detailed but simple to understand explanations of the body processes. The images help me to grasp the concepts and makes learning fun! I really appreciate your help and your sense of humor.😁
I love the intro and the jokes in them xD "it takes guts to learn anatomy" while pointing to the guts "Hank normally wears a helmet, RIDE SAFE," And my favorite "EVEL KNIEVEL IS FROM MONTANA!!,"
informative vid, thx a lot. have u planned to make one on ketosis? i think this is missing - nowadays a lot of people cut carbs in their diet, especially fructose, to lose weight. keep it coming!
How do you learn, keep focus, and remember things? Whenever I read or watch informative sources, my mind start to drift, and after about three or four times I actually start processing. I would like to improve this. Any pointers?
I appreciate the thoroughness. I need a quick summary from my book, this helped. I wonder what happens though for someone like me who needs to need to build muscle and have low blood sugar. I need to eat constantly, it's exhausting.
+Alan Cotter If you is interested in human anatomy the greatest results that I have had was by using the Anatomy Blueprint Pro (just google it) definately the no.1 course i've tried.
Except this spelling and grammar test. "Passed" and "tests" are misspelled. Also, you used a run on sentence. Sorry, the irony was too tempting. I blame it on my English major education.
This guy and channel are amazing!!! Such good info and the way they pack it. Thank you - but yeah, I have to put speed on 0.75 to have it in normal tempo lol
Wow, this is so interesting! Definitely one of those videos I will be watching repeatedly until I can remember and absorb a solid chunk of knowledge :) Thaaaanks!
Hello. You mentioned that in the post-absorptive state, the body launches gluconeogenesis in order to restore the blood glucose levels by making glucose from amino acids. However, I assumed that in the post-absorptive state, your body would want to break down the storage glycogen to produce glucose through glycogenolysis. So my question is, why does the body prefer gluconeogenesis in this state over glycogenlolysis? Thank you.
The very last part is slightly incorrect. Weight loss is caused by the ketogenic state from cells not being able to use the insulin to, more or less, shuttle the glucose into the cell.
very good. Can you separate the nutrients that have reached your blood from the blood itself? Does blood always have some nutrients in it as long as you are alive?
At 3:00 there's one hydrogen too much for the second stage to be a fructose derivate and consequently its upper little metabolite to be called a dihydroxyacetone.
Gluconeogenesis can only work on amino acids. Fats can't be made into glucose by the body: instead an alternative energy source (ketones) can be made in the liver and keep the brain alive when glucose and amino acids aren't available.
+Shiny Afro Huh, news to me. Thanks! I'll have to update the way I teach metabolism. I am correct in believing that the reason our bodies have to switch to ketone bodies in the absence of any carbs/protein is that simple fatty acids cannot be converted into sugars, right?
8:00 - Low blood sugar damages the brain? Can someone elaborate here? I'm on keto, tbh I feel like I have more energy, a more consistent energy curve and I have better mood stability in general.
Your brain will demand a very small amount of carbohydrate even if you aren't eating any, which your liver makes from protein or glycerol via gluconeogenesis. (your erythrocytes actually need glucose, whereas neurons mostly just prefer it, but erythrocytes have tiny demands) But it'll get the majority of its energy from ketones. If your brain can't get energy, it'll get damaged.
The neurons can not only rn exclusively on glucose. About 60% of their energy can come from ketones(fat) and it even has some improvement in cognitive function. The rest can always be made by gluconeogenesis
These are some of the best videos, this one is good but didn't touch upon ketone bodies which is v important result in free fatty acid catabolism. Perhaps it's covered in another.
so what i have come to realise is body fat is more like a backup battery than anything else and blood sugar content is like a capacitor and the digestive tract is like a power generator with food being the fuel isnt it weird that the body can be so easily compared to a machine
Ketosis is basically when Acetyl CoA (product of glycolysis) cannot continue to be made into energy through normal metabolism - so your body turn it into ketone bodies - which supply fuel for the brain, too much ketone bodies effect the pH of your blood buffer system causing ketoacidosis (hope this helps)
the first molecule you refer to as fat is actually glucose. fats are generally in a form of triglyceride plus fatty acid chains. This also need to be converted into AcCoa before it can actually be used for general oxidation. Just thought a small correction might be needed.
When you run out of glycogen your body goes into a state of nutritional ketosis where our mitochondria oxidized fat for fuel. you need dietary protein for gluconeogenesis in the liver if you have no dietary sources for 2 days how are you going to get this. in the medical literature it has been cited that fasting does not elicit catabolism explicitly or deleteriously to your muscles. Is this also what autophagy is for.

the graphic animations are always so cute they're honestly the best part of crash course
you have also fallen in love with the pancreas?
I play most youtube videos at 1.5x speed. Crashcourse is 0.5.
so true
this is no lie

I'm so glad you have helped me discover this part of youtube! Yay!
One time I saw Hank Green in the Good Food Store in Missoula and it was the best day of my life
If I could, I'd give this a million likes. I can't like it enough. A single "like" is terribly insufficient.

everyone needs a guy like Hank in their lives to make everything interesting !
This series is really helping me out with the nutrition course I'm required to take! Thank you guys for your hard work.
LOL! Nice Rick and Morty Lil' Bits reference at 8:56 !

I watch these before every A&P quiz, Hank will be responsible for my nursing degree.

Great work guys! Learning more here than I do in University!
This is by far my favourite CC-series!
Ive never learned more than I have while re-learning all this stuff we should learn in school.
This is by far my favorite channel on RUclips!!. Would love to have these videos in Spanish though. I could even help translating if you want :D
I like the way you talk, it's so fast but still easy to hear, I'm so excited, thank you 😂
Try clicking on the settings icon, then adjust the playback speed. That's what I do. They assume the viewer has no attention span.
Yet again, making uni lectures understandable!
I love Crashcourse. The only thing I would add is a few test questions at the end. Thanks Hank and CC family. DFTBA
Great videos!! Where does Ketosis fits in this scenario?
It took me years of reading to get to understand the stuff that is so expertly depicted in this video. What an amazing presentation!
7:57 and if that fails it starts a process known as Gluconeogenesis Evangelion
GET IN THE HDL PROTEIN SHINJI
The fourth sugar impact
I love this so much! Thank you for making such amazing vids!!

I speed up the video, which makes it way easier to focus.
I really like this. I’m in college for nutrition and it helps me so much. He’s so helpful
I appreciate the thoroughness. I need a quick summary from my book, this helped. I wonder what happens though for someone like me who needs to need to build muscle and have low blood sugar. I need to eat constantly, it's exhausting.
This guy has saved my grade way too many times
This video helped me write a term paper in 24 hours.
I want CC World history to return :(
+Alan Cotter not the only one
me too :/
+Alan Cotter Maybe after he's done writing his book.
it's what got me into the channel.
+Alan Cotter If you is interested in human anatomy the greatest results that I have had was by using the Anatomy Blueprint Pro (just google it) definately the no.1 course i've tried.
Thank you crash course for making A&P fun for me!! I love youu guysss hahaha
Hank Green my angel
I really like your fast and dense presentation of information.
You are the reason why I past all my test, thank you!!!
Except this spelling and grammar test. "Passed" and "tests" are misspelled. Also, you used a run on sentence. Sorry, the irony was too tempting. I blame it on my English major education.
FAAAAAAAACTS
@@someguy2135 I bet she had passed an English test after your mention :DD
@@MaruskaStarshaya Maybe it was constructive criticism. By the way, the math majors made fun of me for my lack of math skills.
@@someguy2135 I wonder where are you from because Americans and Europeans usually don't care about someone's grammar and skills.
This guy and channel are amazing!!! Such good info and the way they pack it. Thank you - but yeah, I have to put speed on 0.75 to have it in normal tempo lol
I love this ! please make more and in this direction (medicine , human anatomy )
definitely, without doubt!
Can you explain the process of ketosis?
this is awesome, you can come to teach at my college!!
Wow, this is so interesting! Definitely one of those videos I will be watching repeatedly until I can remember and absorb a solid chunk of knowledge :) Thaaaanks!

THIS IS AMAZING, I love youtube and the creators like thissssssssssssssss
These videos are amazing but for someone like myself with dyslexia it's very fast pase so I have to watch them up to 4 times.
Wow, you just blew my mind with all that content....Am amazed, need time to digest.
These videos are brilliant!
Not gonna lie, I'm watching this at 0.75x speed. Btw this is such a useful video. I have to rewatch to really remember all details
The very last part is slightly incorrect. Weight loss is caused by the ketogenic state from cells not being able to use the insulin to, more or less, shuttle the glucose into the cell.
You should do a biochem playlist! ;)
I actually learned a lot from this video!!! Thanks Crash course!
That intro was pretty awesome
very good. Can you separate the nutrients that have reached your blood from the blood itself? Does blood always have some nutrients in it as long as you are alive?
yeah, I'm betting with a centrifuge and destilation. And as long as you eat you will.
for a period of time your blood will have nutrients in it after death unless you died to the cause being lack on nutrients.
I'm trying to learn the lymph system and immunity for school and it is so confusing. I hope you're planning videos about that soon!
You sir, are brilliantly intelligent and extremely helpful! Much appreciated!!!
+Jeff Wilson He is, but just remember its a team effort. He is pretty much reading a script.
great video! thanks
Thank you so much
Love this channel, keep up guys
Also asking for details on Keto or the effects of intermittent fasting. Thanks as always for the effort CC puts into its lessons!
At 3:00 there's one hydrogen too much for the second stage to be a fructose derivate and consequently its upper little metabolite to be called a dihydroxyacetone.
'And brunch is as good a place to start as any... other than breakfast of course.'
Great Video, thanks
Nice Rick & Morty reference at the end there, Thought Cafe xD
litlle bitsssss
So much learning, so much fun. Hank, why is LDL bad?
It's time to learn Anatomy & Physiology! NOW!
Oh, wrong channel.
Do a series about Ketosis and fasting and its health benefits and longevity.
I can't wait to learn this in college
lol true I was just at Pepperdine and I'm only 13
FUCK OFF LITTLE NIGGA, jk grants
so should you be eating 3 meals a day or smaller meals through out the day?
you help me with my classes THANK YOU SO MUCH I LOVE YOUR TEACHINGS
Video suggestion: I'd love to see a crash course on the body on ketosis (via a keto diet)
Using fat for energy is good and one of the best ways to stay healthy.
This is a truly remarkable video. Thank you very very much! :))
Omg just discovered there are Crash Course flash cards!!!! Just how far in my post grad studies will crash course get me? 🤔
Watching this while eating dinner :)
Gluconeogenesis can only work on amino acids. Fats can't be made into glucose by the body: instead an alternative energy source (ketones) can be made in the liver and keep the brain alive when glucose and amino acids aren't available.
This is an important point that I feel deserves to be mentioned in a video about metabolism, yet, sadly, it was only vaguely alluded to.
+Shiny Afro Huh, news to me. Thanks! I'll have to update the way I teach metabolism.
I am correct in believing that the reason our bodies have to switch to ketone bodies in the absence of any carbs/protein is that simple fatty acids cannot be converted into sugars, right?
I think glycerol can be converted to glucose but the fatty acids are not.
That is not exactly true, Gluconeogenesis works with Lactate, Amino acids and the Glyceride portion of Triglycerides the basic Fats.
Helping as much i can

It's not them, it's a fake.
Keep GOINNNNNNNNNNN
so what i have come to realise is body fat is more like a backup battery than anything else and blood sugar content is like a capacitor and the digestive tract is like a power generator with food being the fuel
isnt it weird that the body can be so easily compared to a machine
why did you not include a break down of ketosis? seems like a very important part of your metabolism
thankyou so much!! !love it
carbohydrates increase your basal metabolic rate, this means that sugar are not very fattening and instead help you lose fat.
Please do a CrashCourse on Ketosis! I would love to see what goes on.
Ketosis is basically when Acetyl CoA (product of glycolysis) cannot continue to be made into energy through normal metabolism - so your body turn it into ketone bodies - which supply fuel for the brain, too much ketone bodies effect the pH of your blood buffer system causing ketoacidosis (hope this helps)
