    I remember watching this a couple of years ago for the first time when going through A&P 1, trying for the life of me to remember how the circulatory system worked. Fast forward to now, I'm currently a semester 1 nursing student about to head to my first clinical in a little more than a week. It's crazy how time flew by but I'll always make time for a crashcourse refresher

  • @buffyclark2968

    I do not procrastinate! My class just started this section today. I watch CrashCourse first, get a general overview, then go into more and more detail. CrashCourse is not just for students who didn't study, it is also for people who are studying.

      CrashCourse Isthere any danger to having two hearts? Because if I had the money I would have an artificial heart installed in my body alongside my normal one, exactly for this reason, vulnerability.

    • @komali100
      @komali100 9 ปีที่แล้ว +53

      zoranhacker Humans are surprisingly very tender and can die from just a small part of the body going out of whack. The amazing thing is how our bodies naturally regulate themselves so well that we are able to live. Really, I think the more you watch this series, the more you will feel like, "Way to go, body! Way to go."

    • @sacr3
      @sacr3 9 ปีที่แล้ว +18

      zoranhacker Don't, the hearts been evolutionarily tested for millions of years and typically the "bad hearts" would fail before the Human could procreate, so the odds of you having a gene that causes heart failure at a young age is all but gone.
      But your lifestyle will affect its performance down the road, so take care of yourself bud.. I didn't, I don't have a heart condition just yet but i'm sure I will and its not a good feeling to be worried about your ticker.

    • @zoranhacker
      @zoranhacker 9 ปีที่แล้ว +6

      sacr3 I'm aware of the level of perfection that our bodies are, and I didn't say I was reasonably feeling vulnerable, I just was. And why are you so sure you will have a heart condition? Whatever it is that's bad about your lifestyle can change if you want it to, which I don't see why you wouldn't if the other option is getting a heart condition.

      Heartbreaking is real.. your heart has it's own brain cells aswell.. Aztecs, Egyptians and many more ancient cultures knew this but modern western doesn't approve that but more and more were finding that the heart has more powers.. the most important thing to know is that God check ones heart when we die so keep it pure🙏

    How to break a heart (let it go)
    The heart on call 24 hours a day.
    It is work all throughout the night.
    If it sounds like walking on cold snow.
    We will rush you to the ER.
    It's building pressure up inside.
    Gonna let go, through the atrial valve.
    Don't eat that cake.
    Eat healthy food.
    Go to the gym and skip the chips instead produce.
    Otherwise you heart is screwd!
    Let it be.
    It will beat
    Even if you don't think of it.
    It is your true love.
    Whiteout it you would be dead now!
    It dosent care about what your crush just said.
    Its only job is keeping you alive.
    Hey Hank I expect you to sing this on at least one of you channels. This video gave me goosebumps. Guess I made the right choice to be an MD! Love heart sounds.

    And this is why I love you! My pharm students start drugs for angina and heart failure tomorrow, and then I'll have them watch this, and then we'll do hypertension next week. You folks save me valuable class time (and time I would spend making my sad little videos) that I can now use for active learning and case studies. Thank you, thank you! I do also like that you include little shout outs to pathophysiology like the effects of long term hypertension and congestive heart failure. It makes learning the A & P so seem much more relevant to students starting out in the health sciences!

    Dear John, I've been graduated from high school for 5 years now (god it's been so much longer than it feels), and I recently was reminded by you that it was you in crash course all those years ago. I downloaded all of them and am now listening through it during work, learning is fun when you're not being forced to.

    P.S. last time we translated subtitles, they were never put up, so we really hesitated to try again since it took lots of effort and time:( let's hope they are not so busy this time :(

    I'm a medical student and have a pretty strong stomach for most things but for some reason I just hate hearts - to the point where I've passed out dissecting one. It seems so irrational considering the importance of our and the fact that other organs are absolutely fine for me, but the thought of hearts or the just hearing the sound they make makes me freak out. Great since I'm going to be a doctor, amirite? Loving the anatomy series, helps me recap things I've learned and is funny and interesting. Wish I had these videos back when I was doing my A level biology.

    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.

    (Verse 1)
    I had a broken heart, I thought it was love
    But it was just my blood pressure rising up above
    I thought I'd never mend, I thought I'd never thrive
    But then I learned to manage, and now I'm feeling alive
    (Chorus)
    I've got a broken heart, but it's not from love
    It's from high blood pressure, from stress and stuff
    I take my meds and I watch what I eat
    Now my heart is mended, and I'm feeling fleet
    (Verse 2)
    I used to worry all the time, my stress was through the roof
    But now I take it easy, I've learned to be aloof
    I exercise and I eat my greens
    And now my heart is healthy, and my blood pressure clean
    (Chorus)
    I've got a broken heart, but it's not from love
    It's from high blood pressure, from stress and stuff
    I take my meds and I watch what I eat
    Now my heart is mended, and I'm feeling fleet
    (Bridge)
    Don't let high blood pressure bring you down
    There are ways to manage it, don't let it get you down
    Take care of your heart, and it will take care of you
    You'll be feeling healthy, and your heart will be brand new
    (Chorus)
    I've got a broken heart, but it's not from love
    It's from high blood pressure, from stress and stuff
    I take my meds and I watch what I eat
    Now my heart is mended, and I'm feeling fleet

      +CrashCourse I highly disagree with you regarding "the heart is just a pump". Science is still not sure if the heart feels or not. But recently many researchers cannot explain why heart receivers feel and change their beliefs just like their heart donors.
      However, I believe that heart actually controls our brains through neurons connection and I can't wait to prove this via lab experiments.

    • @chris7247
      @chris7247 7 ปีที่แล้ว +1

      Yes, it is possible. And no, they don't live because they're already dead. Heart donors are people who have recently passed away and gave their consent before they died.

    What's the Point?
    My heart, your heart...
    they all look alike,
    two puffy mounds at the top,
    tapering down into a spike.
    But just why is it
    that they all look the same?
    Shouldn't a person's heart be
    as individual as his name?
    Well, if you look a bit closer
    you will readily see
    that everyone's heart is
    just as different as he (or she!).
    For it's not the shape,
    nor even the size,
    But what's inside
    that is truly the prize.
    The mound on the right...
    holds memories so dear
    only the good ones
    from year after year.
    And the mound on the left,
    is filled to the brim
    with the light of sweet passion,
    that never grows dim.
    Now the part in the middle,
    is where deep love resides.
    Its strength can be fierce,
    Yet here, too, fragility hides.
    Then finally, slowly,
    the heart slopes to a fine edge..
    coming to a sharp point
    in the shape of a wedge.
    This point is for balance
    between all the parts
    which is very important
    for those with full hearts!
    And if you look more closely
    you will see right at the tip
    a tiny little hole
    no bigger than a pin.
    This is the place
    where all our sorrows go
    They stay with us a short while,
    then seep out with the flow.
    Hearts can be lonely,
    Hearts can be sad...
    Hearts can be faithful,
    In good times and bad
    But no matter the shape,
    Nor how big or how small,
    Your heart is a gift,
    To be shared with all.

    • @genteelsatyr
      @genteelsatyr 9 ปีที่แล้ว +21

      KindessisEternal I've a condition which messes with my valves, and the right side of my heart. I like to think I have a reasonable grasp of how hearts generally work (and the particular way that mine doesn't work so well) and I enjoyed watching a video which explained things so clearly. I'm hoping from the title of the next video that it might talk more about the beating of the heart. I'm interested in the way that the heart's natural pacemaker works, and the way that my pacemaker replaces that function when it goes awry.
