So we all know that breathing is pretty important, right? Today we're going to talk about how it works, starting with the nameless evolutionary ancestor that we inherited this from, continuing to the mechanics of both simple diffusion and bulk flow, as well as the physiology of breathing, and finishing with the anatomy of both the conducting zone and the respiratory zone of your respiratory system.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

  • @robscallon
    I'm so conscious of my breathing while watching this
  • @bozosaurus666
    I've just recently quit smoking cigarettes and watching these videos makes me feel so happy to be smoke free
  • @danieldong7479
    Anybody here watching this for an online school assignment while in quarantine cuz of COVID-19?
  • @sgw1712
    I have problems concentrating and making myself study... essentially I couldn't do it. Until these videos... thankyou for making educational videos that are done in an engaging and friendly way : ) Things like this are the only way I can study. : )
  • @kayelle1741
    Okay but really, this channel is the only reason why I passed my Anatomy and Physiology class.
  • @chainman624
    I’m watching this 1 hour before an exam…….. 😅
  • This was even helpfull for me, a university med-student, I have been reading 3 anatomy and physiology litteratures in order to learn everything, then you came with this video making me understand almost every important concept in a fun and easy way ! you deserve a lot of credits ! love ur channel, and here you get one more subscription !
  • @medjed2511
    why doesn't oxygen learn parkour then it can get over the obsacles easier
  • The only reason I still have hope for my future is because Crash Course exists.

    6:24 I'm pretty sure that sharing the throat for breathing and swallowing IS IDEAL, as anyone with a bad cold can tell you. It's really, really good that we aren't restricted to ONLY breathing with our nose and swallowing with our mouth. Like really good. We'd all be dead.
  • Its amazing, how intelligence is necessary to understand how all this works, but not necessarily to develop the system itself.
  • @wisperone11
    Thanks! Your videos have proved priceless when teaching my EMTs. It makes it so easy for them to understand. They are fun and full of so much info. Now that you have the apps, I have sent that info onto my class to help them study for their EMT Class
  • @Hyperian
    thumbs up if you were breathing consciously the entire video
