    quick tip for ya'll who have a hard time watching it cuz he's going to fast: change the speed in the video to 0.75 and he's actually talking at the speed of a normal human. Really helped me out

    It would be nice if you slow down a little so someone could process what you are talking about, besides if no one get's it because you're talking to fast, what is the point??

    So when we learned in Rick and Morty that "Wubba Lubba Dub Dub" means "Help me, I'm in great pain", we know that Rick has a heart arrhythmia.

    No joke this has helped me more than actually going to class. I go to my tutorials and the tutors expect us to know everything already AND to make class "interesting" instead of making small relevant jokes, they literally just tell stories. Best part, I can literally just watch this at home and not have to attend since attendance isn't required for the theory classes.

    a heart can break from someone dumping you and that condition is called Takotsubo cardiomyopathy.

    I think it would be better to think again about what the heart is... is not only a pump and just a pump, new studies reflect more subtle aspects of it like for example that it also has neurons.... thanks

    Question Dissections occur in high schools across the country. The vast majority or any specimens needed is very high. With that number in mind , do you agree or disagree that dissections should be occurring within classroom across the country. If yes, please discuss the benefits, drawbacks and how we can be sustainable and respectful to life. If no, please discuss the benefits and drawbacks and how we can replace the use of dissections within the classroom as a teaching tool.

    Love the videos from Crash Course in general but always on the downside, you are speaking way too fast. Which makes it really unhelpful for me..

    When exams role around, my classmates desperately scramble to begin their scatterbrained frenzies in an effort to regurgitate facts and figures about the inner workings of the human body. Meanwhile, I say it's time for a Crash Course marathon.
