the graphic animations are always so cute they're honestly the best part of crash course

[@danielwatson6529]

you have also fallen in love with the pancreas?

[@daancer1997]

One time I saw Hank Green in the Good Food Store in Missoula and it was the best day of my life

[@Stevo1361]

I play most youtube videos at 1.5x speed. Crashcourse is 0.5.

[@olgailina90]

so true

[@diamondcupcakess]

this is no lie

[@madLphnt]

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.

[@clairec9745]

I'm so glad you have helped me discover this part of youtube! Yay!

[@TaiChiKnees]

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? :-)

[@juanitaw156]

TEACHER, GET OUT OF KZbin!!!

[@federicahibiscus]

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!!

[@moosharmy101]

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

[@amandawilliams7488]

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.

[@ouafallouz]

everyone needs a guy like Hank in their lives to make everything interesting !

[@erikkunchan]

LOL! Nice Rick and Morty Lil' Bits reference at 8:56 !

[@tomus0n]

This series is really helping me out with the nutrition course I'm required to take! Thank you guys for your hard work.

[@hudamahdi3703]

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 !!!!!

[@jaimie00]

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 🙃

[@yugiohfan101ful]

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!!,"

[@DaylnBryant]

Great work guys! Learning more here than I do in University!

[@infitnesslovbymariasalinas6360]

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.😁

[@ol7505]

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.

[@dwig-6188]

I like the way you talk, it's so fast but still easy to hear, I'm so excited, thank you 😂

[@someguy2135]

Try clicking on the settings icon, then adjust the playback speed. That's what I do. They assume the viewer has no attention span.

[@valeriafoster2670]

This is by far my favorite channel on KZbin!!. Would love to have these videos in Spanish though. I could even help translating if you want :D

[@SuperSprigs]

Ive never learned more than I have while re-learning all this stuff we should learn in school.

[@lucyLou412]

Yet again, making uni lectures understandable!

[@willuexwilluex6241]

I love Crashcourse. The only thing I would add is a few test questions at the end. Thanks Hank and CC family. DFTBA

[@lagoonroom4600]

I love this so much! Thank you for making such amazing vids!!

[@Figaroblue]

It took me years of reading to get to understand the stuff that is so expertly depicted in this video. What an amazing presentation!

[@Morchebab]

This is by far my favourite CC-series!

[@dariusshahdoust]

I love this ! please make more and in this direction (medicine , human anatomy )

[@georgehenna]

definitely, without doubt!

[@googleplay9522]

Great videos!! Where does Ketosis fits in this scenario?

[@fuechen545]

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!

[@kulotz5555]

Hank Green my angel

[@bridgettstar1]

You are the reason why I past all my test, thank you!!!

[@someguy2135]

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.

[@MichaelCordero]

FAAAAAAAACTS

[@MaruskaStarshaya]

@@someguy2135 I bet she had passed an English test after your mention :DD

[@someguy2135]

@@MaruskaStarshaya Maybe it was constructive criticism. By the way, the math majors made fun of me for my lack of math skills.

[@MaruskaStarshaya]

@@someguy2135 I wonder where are you from because Americans and Europeans usually don't care about someone's grammar and skills.

[@summah7283]

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

[@brittanyhohenadel3782]

This guy has saved my grade way too many times

[@lizziefashionlover]

I really like this. I’m in college for nutrition and it helps me so much. He’s so helpful

[@Fitzrovialitter]

I really like your fast and dense presentation of information.

[@SeaUrchinZone]

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.

+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.

[@MeleDrummer]

this is awesome, you can come to teach at my college!!

[@S1ythern]

Also asking for details on Keto or the effects of intermittent fasting. Thanks as always for the effort CC puts into its lessons!

[@MaryMary-sn7hh]

Thank you crash course for making A&P fun for me!! I love youu guysss hahaha

[@alysiarenfroe156]

You should do a biochem playlist! ;)

[@Wonderandthunder]

This video helped me write a term paper in 24 hours.

[@KhontentKueenKameka]

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.

[@fadhilinjagi4694]

Wow, you just blew my mind with all that content....Am amazed, need time to digest.

[@leroy99]

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

[@jeffw825]

You sir, are brilliantly intelligent and extremely helpful! Much appreciated!!!

[@DavidEnvy]

+Jeff Wilson He is, but just remember its a team effort. He is pretty much reading a script.

[@let4be]

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!

[@jchidi]

I actually learned a lot from this video!!! Thanks Crash course!

[@LucyBallou]

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.

[@sallyhutchins1]

These videos are brilliant!

[@samiapassos9659]

Using fat for energy is good and one of the best ways to stay healthy.

FUCK OFF LITTLE NIGGA, jk grants

[@jasonsfamilyandfriendsvide3227]

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.

THIS IS AMAZING, I love youtube and the creators like thissssssssssssssss

[@EndPur]

Great Video, thanks

[@djbrasier]

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.

[@williecrook1279]

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.

[@djbrasier]

+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?

[@amyallen-chabot9753]

I think glycerol can be converted to glucose but the fatty acids are not.

[@polytoxicomania5775]

That is not exactly true, Gluconeogenesis works with Lactate, Amino acids and the Glyceride portion of Triglycerides the basic Fats.

[@LetsTakeWalk]

It's time to learn Anatomy & Physiology! NOW! Oh, wrong channel.

[@barbellbilly]

This is a truly remarkable video. Thank you very very much! :))

[@OptimusSime]

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.

[@morganburke7471]

I love this channel and the shows it produces! thank you for all the hard work you guys and gals put into making this amazing program!

[@LuisGarcia-wm2lh]

Can you explain the process of ketosis?

[@TheWriter960]

Did You Know? Anaerobic Cellular Respiration creates Lactic Acid! When it does, the Lactic Acid is stored in your muscles, which is why people who are new to working out or people who work out rarely get sore muscles. The more you work out, the more efficient your cells become at Aerobic Cellular Respiration, which is why people who work-out a lot don't get sore!

[@qhack]

Only five trips to the buffet? Blasphemy, I need at least 7 or 8. On an unrelated note, I wonder why my clothing is shrinking.

[@wilfordbrimley8875]

[@hahahwhat]

[@sbellaharris]

Do a series about Ketosis and fasting and its health benefits and longevity.

[@UntamableHG]

Mitochondria is the power house of the cell

[@matthewk3700]

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.

[@autosome2482]

Please do a CrashCourse on Ketosis! I would love to see what goes on.

[@rachelbrawn3383]

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)

[@t33ny76]

Omg just discovered there are Crash Course flash cards!!!! Just how far in my post grad studies will crash course get me? 🤔

[@PyroManiac2342]

HAHA why is Strong Mad on his desk!?!

[@florianpeter7045]

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

[@tadisettitejashree2698]

Thank you for this wonderful vedio sir

[@GrassrootsHerbs]

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!

[@nickskywalker2568]

Video suggestion: I'd love to see a crash course on the body on ketosis (via a keto diet)

[@mwbgaming28]

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

[@Ple781]

you help me with my classes THANK YOU SO MUCH I LOVE YOUR TEACHINGS

[@TheZeyon]

Lil' Bits Rick and Morty references lol

[@legistergregory8108]

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?

[@diablominero]

I speed up the video, which makes it way easier to focus.

[@novaksepelj1731]

One correction - your neurons are not exclusively fed on glucose, they can use ketone bodies as substrate.

[@tatsuroida]

Great video. Slight correction: With rare exception, people with diabetes take insulin BEFORE eating.
