what about the boundaries of muzzle fibrin like A boundry
dude!! too much assassin's creed
Are you still making these videos HanK?
Thank you so much for your videos. They are so much help! I like the way you compare processes of the body with other scenarios.
Made so much more sense than the 4 times my instructor went over it in class. Thank you!
"pent up frustration" "groping" this dude is really thirsty amirite lmao
I сouldn't be аnу hарpiеr with thе results. I gainеd 12 lbs of musсlе in 4 wееks . Nо Sрррeсial Diеt, No Intense Ехеrсise.. https://twitter.com/9b7e19512eee5d182/status/822770372575563776
Why don't you eat the chicken? 3:27
make a video about types of tissues
WOOOO! Assassin's creed!
Thank you for taking something complicated and making it understandable and humorous.
Almost the same episode as the new one but still worth watching.
Hank saved me once again from failing my biology test ?
Were you on Cyberchase?
Now I feel really guilty doing any unnecessary movements, wtf 😀
Thank you so much for this awesome episode!!! And the result that I got was also fantastic! The first time I got 100% in my Biology assessment!!! Thanks again for crash course!!! Keep on doing it!!!
I am a middle school student and that was offensive. 5:20
Your video game muscles ?
I accidently clicked this video and then stopped it at 0:03
I've never laughed so hard xD
You have no idea how appreciative I am of this channel. It's helped me go through A&P, Microbio, Bio l and now finally…bio ll ? you guys are a godsend
u remember the goof ol' days when hank taught us instead of "new hosts" on pbs digital learning
you are freaking also i love it
he makes it so easy to understand-I thank you for that
The knowledge was known, centuries before the Huxley family. We've been told so many lies. "Brave New World: Revisited." Is becoming a reality.
love him he has helped me more then you know-thank you
THIS IS THE BEST
awesome
I laughed when Hank said "because of chemistry" because the title says CrashCourse Biology 🙂
hmmmm this rwminded me of hydoulics so i had an idea of doing some research on making a muscle substitute…then i though of boilagy but the cells would die out then i got the idea of tampering with those cells that keep your cells alive…..then zombie apocalypse came into my head…..i said nope and gave up on that on the spot….oh amd im 13
1:33 thickkk
trash
Where did Hank find that stunt double to work out for him?
how do muscles get built after excercise?
Human body so complicated yet works flawless
why does calcium unbind from troponin?
I have been struggling to understand this for over a week, and you managed to explain it clearly in 12 minutes. Well done. Very well done.
Biden: Ananussayswhat
Trump: "What?"

I love you guys so much. Bless
