That's awesome, %name. Having you understand it is a win for me. That's why I made the video. So many people struggle with the cardiac cycle. If you want to go even deeper, check out this more extensive video that I made - th-cam.com/video/toZI5997hz8/w-d-xo.html.. And if you aren't already subscribed, I highly recommend it. I have a lot of good stuff coming on the cardiovascular system. It seems to be something a lot of people need help with so I'm gonna dive really deep into it.
This is EASILY... THE BEST.... and MOST concise explanation I have heard in all my life. WOW! When I tell you I have taken 3 courses that explained cardiovascular physiology, anatomy and pathology, and I am TODAY years old when I spent less than 10 minutes watching your video and I now feel all those synapses coming together. I feel comfortable enough to explanation this to my peers. THANK YOU KIND SIR! You are doing God's work
Wow Equanimity, I'm so glad this video helped you to understand the cardiac cycle. That's awesome. Btw, after subscribing to the channel, you should definitely check out the rest of my cardiac cycle series. It goes into more depth and I think you'll find it very helpful. Here's the link to the first video - th-cam.com/video/LzWQkxqwans/w-d-xo.html. Enjoy!
I'm a first-year medical student, and I have my physiology exam next week. studying CVS was super difficult but now that I saw your videos, I can't thank you enough. thank you so much for your effort and hard work, I understood it so easily when I was struggling for a week, thank you 😍😍😍
You are very much welcome @@MannatGupta-ml2mn. Glad you got value from it. Make sure to subscribe to the channel, because I have a lot more content like this coming to help you understand how the human body works 👍🏽.
I’m a first year right now and we just started cardiology and this unit had already started to feel like the death of me. I just want you to know that this video genuinely made me confident in my ability to learn this. You may not see this but you just got a subscriber. Thank you!
Woohoooo. That's awesome to hear, Amen. Glad you found it helpful. If you wanna go even deeper in the cardiac cycle, check out this video where I go into a lot more detail - pulse.ly/jr4b7nxla7
I just want to say i appreciate you and your videos so much! I stood up late watching these videos hopelessly around youtube until i landed on your page and realized that you literally made everything my instructor spent weeks on so much more clear and straight to the point. I was really beginning to question my abilities and my stress levels were sky high. I watched all videos for cardiovascular system in less than 24 hrs. THANK YOU! I wish you did microbiology too, you're definitely good at what you do!
Wow, that's so awesome to hear, Fiolla. I know that it can be easy to question your abilities when you just don't seem to get it. But trust me - you can get it. It just takes a different way of looking at things sometimes. You can do this. I'm glad you found my channel and that it was helpful. Make sure to subscribe for more like this. I actually have more cardiac cycle content coming up over the next few days. I'm sure I'll get to some microbiology at some point, but it won't be for a while.
you are the best I am from Libya and second-year medical student studying physiology right now and I have never seen somebody explain it like that easily and simple, so happy from TH-cam for that recommendation, I will never forget to subscribe, hope you luck continue that great content
OMG I'm currently studying for the IBO in 2024 and I have to admit that the way you breakdown the diagram is so much easier to have a deep understanding about cardiac cycle. Love it man! Keep up the good work!
Wow CMMSS, I'm so glad this video helped you to understand the cardiac cycle. That's awesome.

I was in the first year as a medical student when you explained brachial plexus...Now I am ready to pass out as a medical doctor still this video was helpful thanks. But I suggest giving some info about aortic pressure curve as well so we can understand why aortic valves close and when they do so.
I am a 2nd year medical student; when I say you are the FIRST person in my ENTIRE LIFE to explain something so PERFECTLY(I wish there was an even better word than perfect haha)!!!!!!! I understood you EVERY step of the way. You are down to earth and you make learning feel relaxed and calm and not stressful! You are changing lives #supporter #suscribed
Oh wow, Ary. You have no idea how encouraging that is. This comment is the exact reason why I started this channel. I want to help people understand this stuff because I believe that so many professors make it too complicated to understand. So I'm glad to help in whatever way I can. And thanks for subscribing.

Ah man, don't be disappointed about that Samantha. That means you are pretty advanced. I WISH I had start learning this stuff at your age. You are being set up for success. I hope you find the video helpful.
lol, age doesnt matter when it comes to learning . Some people get the chance to go to medical late maybe in their 20s or 30s some it is a bit earlier ..I dont even know what is actually bring you pain , anywys all happy learning
I'm an ECHO student in my first week. I was so confused until this video! THANK YOU!!!❤ I have to pretty much know this buy this week so I can move on. I was completely freaked out. You saved me!!

Sure, it's so easy as long as you don't have hundreds of other cycles and processes and adverse reactions and pathophysiology and on and on and on to learn by next Tuesday.
Hey! A 16 year old student from India here...I literally read my book 3 Times already and still wasn't able to cope with it ..Thank God I came across this video.. It's just wonderful for students like us who learn better via videos.. You are a perfect teacher.. thank you for saving my near future 😌
It's so interesting that every younger person who comments on this video seems to be in India. Your educational system there must be pretty impressive.
@@InteractiveBiology Well...Our Education System believes in introducing the complicatively fascinating things at a young age...So that we can easily understand things while pursuing medical...We need to excel in all these in our 11th and 12th for passing the NEET in minimum attempts to clear our way to goverment medical Colleges...So here We are...! 🤧
I am a nursing student preparing for my CVS physiology test. The lecturer did not explain the topic very well he just scanned through a whole of like 300 pages of his pdf. And now I have to start looking for ways to understand Thank you so much for making my work easier I wish you were my lecturer
That's great to hear. Happy to help. Make sure to subscribe to the channel, because I have a lot more content like this coming to help you with biology.
Sir im a first yr med student nd it is more wonderful than any other explanation ive come across so far.. searched around multiple books guyton , ganong … the more heavy the book is the more complex the cardiac cycle becomes😢.. but i can’t believe u explained it with such dexterity nd clarity… U are a saint.. hve to say… ❤ u got another subscriber 🤗 Much love nd respect frm India 🇮🇳 ❤
Wow, I'm so glad you found it helpful, %name. You are so welcome. I'm just trying to be helpful with these videos so I'm glad it's working 😉. Btw, if you aren't already subscribed, I highly recommend it. I have a lot more great stuff coming and if you like this, you'll like those too.
Heyy Im from India, Im just 16 and being almostly faint by cardiac cycle notes but after your classs it just amazing and covers all the topica and its crystal clear ✨✨thanks a lottt the best class in TH-cam 🤍 and i just realized i have to study this in young age cuz the comment section is full of medical students 😅anyway thanks alottt ❤from Kerala
@InteractiveBiology yhhh😅 sometimes it's seem to be proud but sometimes it's the biggest head ache ever , till 10th grade almost 15 years we have to study all the subjects next 2 years we can choose but there also many lot to study even though we didn't need it in future we have to study that subjects 🙆 Indian educational system is quite different btw I appreciate your dedication, you replied me even on 2 years before's video's comment section this meant a lot 🥰❤️✨ I just checked your videos it's so interesting
Yeah that's a lot. But I find you all are wayyy more prepared than the average American. So that can be a good thing. Glad you're finding the videos interested. Stay tuned for more.
Liked subscribed bell icon turned on for notiffs!!!! I'm a 1st Year Medical student at Dundee medical school here in Scotland, I have to say just this single video of yours covered it so well honestly I feel so much better after watching your video!!! I made a transcript of what you said as well, I will memorise the entire cycle using the transcript I made of this video!!!! YOU ARE SIKKKKK!! I'll also watch your longer 23min vid on cardiac cycle I can see it on the side!!! I might've found one of my favourite med youtubers right now!!!

That was sooo easy to understand😊😊😊 I LOVE IT. I was looking for Valve level mechanism translated from Deutsch (Ventilebenenmechanismus) and then, i landed on your video. Thank you so much. I am prepairing for the Nurse Exam and i am happy to watch this video.
Hi Maria, I'm so glad to hear that. I try to make them as easy to understand as possible, while still keeping it at a high level. It sounds like that worked. Stay tuned for more. I have another cardiac cycle video coming this week 😉
Super helpful video!! I have my physiology exam tomorrow morning and this video is super great at breaking down each step, while also keeping it fun and interesting. Thanks!!
You really simplified the cardiac cycle and explained very good, even as i am already a doctor and understand the cycle well, this video is sure really great.
Wow this is amazing !!!! I'm taking A&P 2 and this is what a 6 hour class teaches . You were able to explain it and made it make sense in less than 10 mins !!!!!!! Thank you for sharing

I failed my physiology exam because I didn't understand this topic and I'm about to do resit the exam, I'm amazed because you just broke down everything in my slide, thank you🥺🥺
Cardiac Cycle ( From my biology textbook) How does the heart function? Let us take a look. To begin with, all the four chambers of heart are in a relaxed state, 1.e., they are in joint diastole. As the tricuspid and bicuspid valves are open, blood from the pulmonary veins and vena cava flows into the left and the right ventricle through the left and right atria. The semilunar valves are closed at this stage. The SAN now generates an action potential which stimulates both the atria to undergo a simultaneous contraction-the atrial systole. This increases the flow of blood into the ventricles by about 30 per cent. The action potential is conducted to the ventricular side by the AVN and AV bundle from where the bundle of His transmits it through the entire ventricular musculature. This causes the ventricular muscles to contract. (ventricular systole), the atria undergoes relaxation (diastole), coinciding with the ventricular systole. Ventricular systole Increases the ventricular pressure causing the closure of tricuspid and bicuspid valves due to attempted backflow of blood into the atria. As the ventricular pressure Increases further, the semihinar valves guarding the pulmonary artery (right side) and the aorta (left sidel are forced open. the circulatory pathways. The ventricies now relax (ventricular diastole) and the ventricular pressure falls causing the closure of semilunar valves which prevents the backflow of blood into the ventricles. As the ventricular pressure declines further, the tricuspid and bicuspid valves are pushed open by the pressure in the atria exerted by the blood which was being emptied into them by the veins. The blood now once again moves freely to the ventricles. The ventricles and atria are now again in arelaxed (joint diastole) state, as earlier. Soon the SAN generates a new action potential and the events described above are repeated in that sequence and the process continues. This sequential event in the heart which is cyclically repeated is called the cardiac cycle and it consists of systole and diastole of both the atria and ventricles. As mentioned earlier, the heart beats 72 times per minute, Les that many cardiac cycles are performed per minute. From this it could be deduced that the duration of a cardiac cycle is 0.8 seconds During a cardiac cycle, each ventricle pumps out approximately 70 ml. of blood which is called the stroke volume. The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output. Therefore, the cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and averages 5000 ml.or 5 litres in a healthy individual The body has the ability to alter the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cardiac output of an athlete will be much higher than that of an ordinary man. During each cardiac cycle two prominent sounds are produced which can be easily heard through a stethoscope. The first heart sound (lub) is associated with the closure of the tricuspid and bicuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves. These sounds are of clinical diagnostic significance.

i've been struggling with cardiac physiology for months , can't believe i got it in 10 minutes thank to you ! thank you so much
Woohoooo. That's awesome to hear, Amen. Glad you found it helpful. If you wanna go even deeper in the cardiac cycle, check out this video where I go into a lot more detail - pulse.ly/jr4b7nxla7
I just want to say i appreciate you and your videos so much! I stood up late watching these videos hopelessly around youtube until i landed on your page and realized that you literally made everything my instructor spent weeks on so much more clear and straight to the point. I was really beginning to question my abilities and my stress levels were sky high. I watched all videos for cardiovascular system in less than 24 hrs. THANK YOU! I wish you did microbiology too, you're definitely good at what you do!
Wow, that's so awesome to hear, Fiolla. I know that it can be easy to question your abilities when you just don't seem to get it. But trust me - you can get it. It just takes a different way of looking at things sometimes. You can do this. I'm glad you found my channel and that it was helpful. Make sure to subscribe for more like this. I actually have more cardiac cycle content coming up over the next few days.
I'm sure I'll get to some microbiology at some point, but it won't be for a while.
what's your age?
Yes. You did make the cardiac cycle easy. Many thanks!
Glad to hear it. You're welcome.
you are the best I am from Libya and second-year medical student studying physiology right now and I have never seen somebody explain it like that easily and simple, so happy from TH-cam for that recommendation, I will never forget to subscribe, hope you luck continue that great content
That's so great to hear. Glad you found it helpful. And thanks for subscribing. Stay tuned for many more like this.
OMG I'm currently studying for the IBO in 2024 and I have to admit that the way you breakdown the diagram is so much easier to have a deep understanding about cardiac cycle. Love it man! Keep up the good work!

I was in the first year as a medical student when you explained brachial plexus...Now I am ready to pass out as a medical doctor still this video was helpful thanks. But I suggest giving some info about aortic pressure curve as well so we can understand why aortic valves close and when they do so.
Glad to hear that the content has been helpful. That's awesome. And thanks for the suggestion. That's a great topic to cover.
Can you please brief your suggestion..? It would be helpful..
I am a 2nd year medical student; when I say you are the FIRST person in my ENTIRE LIFE to explain something so PERFECTLY(I wish there was an even better word than perfect haha)!!!!!!!

I notice a lot of people in India are studying this at a young age. Very interesting.
@InteractiveBiology yhhh😅 sometimes it's seem to be proud but sometimes it's the biggest head ache ever , till 10th grade almost 15 years we have to study all the subjects next 2 years we can choose but there also many lot to study even though we didn't need it in future we have to study that subjects 🙆 Indian educational system is quite different btw I appreciate your dedication, you replied me even on 2 years before's video's comment section this meant a lot 🥰❤️✨ I just checked your videos it's so interesting
Yeah that's a lot. But I find you all are wayyy more prepared than the average American. So that can be a good thing. Glad you're finding the videos interested. Stay tuned for more.

Cardiac Cycle
( From my biology textbook)
How does the heart function? Let us take a look. To begin with, all the four chambers of heart are in a relaxed state, 1.e., they are in joint diastole. As the tricuspid and bicuspid valves are open, blood from the pulmonary veins and vena cava flows into the left and the right ventricle through the left and right atria. The semilunar valves are closed at this stage. The SAN now generates an action potential which stimulates both the atria to undergo a simultaneous contraction-the atrial systole. This increases the flow of blood into the ventricles by about 30 per cent. The action potential is conducted to the ventricular side by the AVN and AV bundle from where the bundle of His transmits it through the entire ventricular musculature. This causes the ventricular muscles to contract. (ventricular systole), the atria undergoes relaxation (diastole), coinciding with the ventricular systole. Ventricular systole Increases the ventricular pressure causing the closure of tricuspid and
bicuspid valves due to attempted backflow of blood into the atria. As the ventricular pressure Increases further, the semihinar valves guarding the pulmonary artery (right side) and the aorta (left sidel are forced open. the circulatory pathways. The ventricies now relax (ventricular diastole) and the ventricular pressure falls causing the closure of semilunar valves which prevents the backflow of blood into the ventricles. As the ventricular pressure declines further, the tricuspid and bicuspid valves are pushed open by the pressure in the atria exerted by the blood which was being emptied into them by the veins. The blood now once again moves freely to the ventricles. The ventricles and atria are now again in arelaxed (joint diastole) state, as earlier. Soon the SAN generates a new action potential and the events described above are repeated in that sequence and the process continues.
This sequential event in the heart which is cyclically repeated is called the cardiac cycle and it consists of systole and diastole of both the atria and ventricles. As mentioned earlier, the heart beats 72 times per minute, Les that many cardiac cycles are performed per minute. From this it could be deduced that the duration of a cardiac cycle is 0.8 seconds During a cardiac cycle, each ventricle pumps out approximately 70 ml. of blood which is called the stroke volume. The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output. Therefore, the cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and averages 5000 ml.or 5 litres in a healthy individual The body has the ability to alter the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cardiac output of an athlete will be much higher than that of an ordinary man.
During each cardiac cycle two prominent sounds are produced which can be easily heard through a stethoscope. The first heart sound (lub) is associated with the closure of the tricuspid and bicuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves. These sounds are of clinical diagnostic significance.
The best video on the cardiac cycle so far! Thank you for the simplified explanation.
