I know every one does this but THANK YOU FOR HELPING ME PASS A+P.
Amazing!🤭👏🏽 Thank u
I can't believe how well everything was explained. Those animations are awesome. The way the content is organized it's great. When I have to read about different topics for university it's difficult to understand how everything connects together, but here the script it's so clear! At the end everything makes sense.
too much knowledge for GCSEs but it's the best I can do to prepare for it TT
I'm too lazy to stare at a textbook or make flashcards that I won't use.
Crash Course, everyone who likes this wants a cell plushy and doesn't understand why there are any dislikes.
Cell plushies. PLLLLLEEEAAAAAASSSSSSSEEEEE!!!!!!!!!!!!!!!!!!!!
Big applause to this channel. Can't your teaching style and the graphics are too interesting well done crash course team. I have felt very sad why I didn't find this channel when I was studying 12th. This will be very useful for NEET students . Please continue your channel.
amazing. perfectly said ty so much
come to think about it- this is the very definition of Biochemistry.
You are the first person who successfully taught me this topic . Thanks a lot !!!
I’ve watched this at least 15 times in the last 2 weeks for my exam. It’s just so much easier than to read a book that never gets to the point, or to listen to a professor who glazes over it. Thank you!!
this is the one episode I struggle to understand, I just get so so confused, no matter who tries to teach me this, I follow up to a point and then I just miss something, nothing specific, but I just can't concentrate… Crash Course is amazing, the reason I'm passing my Psychology exams haha
As an FNP student, I just have to say thank for you really breaking down this complex subject. I haven't taken an A&P class in over 10 years, so this is such a good refresher. My professors suggest these videos for their students to review because it is explained more clearly than a dull textbook.
I am not a native speaker and can't catch up with English some teachers speak but although you speak fastly sir I get each and every word❤️
Polarization
Depolarization
Plz explain again… Little confused
Didn't know I'd find Hank in a biology video. Shook. Thanks, Hank 😉

bag of battery's*
I think the term your looking for is
electric meat
The noise they played every time they showed the membrane up close was so annoying and distracting
My new favourite channel as a biomedical engineer.
Sounds like thanos.
