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
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.
im a nursing student, and i paid 89$ for this online course for learning anatomy & physiology but your videos often give me a better, more overall understanding!
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🙏
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.
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."
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.
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.
As someone who's had heart problems her whole life, this made more sense than anything doctors have attempted to explain to me, so thanks for that! Really helpful :)
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.
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.
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!
i passed my anatomy class becuz of these videos from crash coarse, thank you for making crash coarse available and free .. i love your voice btw and your fun personality. from NORTHDAKOTA
A thank you to Crashcourse on behalf of parents! I have been showing my kids your videos for years, and now my oldest is in middle school and participates in all sorts of STEM activities without any direct pressure from me. I’m now showing your videos to my kindergartner, and will be doing so for years to come. Thank you again, and happy holidays.
I'm a Physiology PhD with a CV exam tomorrow and the most valuable 10 minutes of my studying has been watching this video. Even material that goes into in-depth biophysics and abstract concepts is given great context by this refresher. High schoolers and medical students alike should watch this when preparing for any cardiovascular exam.
I am currently a nationally certified EMT and felt I needed to brush up on my cardiac knowledge. This video was very helpful and your personality kept me interested (: Thank you!
thankyou guys for the all the work...its really really helping me and my friends to study without getting bored.if any of us have any dought in histology and anatomy we clarify it through your videos...thanks a lottt for your help..and keep it up with it....
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
I watched a ton of CrashCourse during a semester when I had a couple psychology courses (I passed both with one B and one A!) So I came back again now that I have A&P. CrashCourse is definitely a lifesaver. It keeps my attention focused, instead of my eyes glazing over and my brain wandering off like it does during alot of other videos with a very monotone, boring narrator. Thank you CrashCourse ❤️
Crash course,, Wow! As senior clinician i have been really encouraged by your lectures. I feel know i have to contirbute my fair share to the world of Medical Science. Thus, I have uploaded my first PPT based video.
Love these videos, my A/P professor moves so fast through concepts and these videos break everything down so easy! Thanks for making them for the greater good!
The heart has always fascinated me. It's insane to me that so many grown ups don't understand what the numbers in the pressure stand for. I had, however, forgotten how all the arteries and veins were positioned, so thanks for reminding me :D
My goodness! Where have you been? Thank you so much. I was recently diagnosed with a heart issue and this video helped me understand so much I'm almost crying. Again, thanks!
I learn so much from these crash courses. Lectures at my school are too short and boring. This crash course I watch with such enthusiasm. Just love it. Thank you for making A&P easy to learn
I've learned more from these videos than I have from my professors and textbooks, for some reason my brain can just never understand the way they explain things but this... THIS and the animations are a godsend!
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.
Day 16 of quarantine, it is currently 3 am. I now have to learn off of these videos and I’m half asleep trying to get all my work done and now I actually miss public school.
TheFireflyGrave The diagram in my science textbook in primary school had the veins in blue and the arteries in red to make is clear enough to see the difference,
I remember learning about this in my Biology class in college, I was fascinated then by how the heart works, and I still am. It's really an amazing organ.
I hope Hank sees this! 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.
+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.
+Jeseka C Christieson If you is interested in human anatomy the greatest success that I have had was by following the Anatomy Blueprint Pro (just google it) without a doubt the most incredible info i've tried.
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.
Someone has got to write a song about broken hearts by pressure. This is so fascinating! not a student, but a professional ASL interpreter and this is some GREAT SCHEMA!
Courtesy of ChatGPT: (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
at 44 years old, I am getting ready to write my first paper since 1996. A high school grad, but I don't have a high school education. Mattie @ NSCC was here~
HALOUNSC2552 We totally sang it on set shortly before the wrap up. (Unfortunately, not while cameras were rolling, so that one won't make the outtakes. MISSED OPPORTUNITY, I KNOW.) -Nicole
I just love your videos, I am a fan of Crash Course History, but medicine and biology are also great. Keep pushing hard on knowledge guys, greetings from Colombia.
Jorge Cisneros crashcourse is a sponsored channel and they have a team of researchers which are medical professionals that contributes to the videos hank hosts.
Awesome video! Just want to write an small comment to clarify that when Hank said: "and this is the only time in your body where deoxygenated blood goes though and artery", is technically true for an adult. However in the embrionary development the umbilical arteries also carried away deoxygenated blood from the fetus back to the placenta.
Yup Hank you are the man, you need to speak with my Physiology Instructor about presenting a clear, concise, and most importantly informative presentation.............. thankyou
You're so clever but you talk so fast. My college uses you to explain things but most of us can't keep up because the words per second you produce hahaa Such a clever man.
Okay so I missed a couple of science lessons, mainly where my class learned about all this stuff. And you're telling me that it took them a couple lessons to get through everything. And I learned it all in a 10 minute video.
