Mr. Samuels!!!! Small world!!! I googled this topic and chose the first video that came up! I am an AU Alumni (class of 2013) , now I am in medical and really appreciate the help you are sharing in these videos!

I've been searching the web and combing over my books for the best possible explanation to SV... I came across your video and now everything makes sense. Thank you!

You have just made a new fan in Puerto Rico. I found this video so helpful and clear to understand (that's the best part)! I never quite understood how stroke volume was calculated, and thanks to you now I do!

Thank you so much for your wonderful videos! I am a dental student and am watching all of your cardio videos before I get started studying for my physiology exam and it feels great to have a solid foundation on all of this challenging material. Your videos are brief but extremely informative and I really appreciate all of you hard work in putting them together. Best wishes!

I just want to thank you so much for your fun and awesome videos. I just found your channel, and it is really helping me learn and retain the information. I feel very confident about my next exam! THANK YOU & GOD BESS! :)

Your videos are carrying me through Human Physiology! YOU'RE THE BEST

Yayyy. Thanks. Honored to have you as a subscriber.

physiology finals = gonna watch all your vids!! they've been so helpful! hope u never stop uploading! i appreciate all the time u put into making these vids to help students like me who doesn't understand the material right away in class! thank u again and God bless:))

You made this so easy to understand. Thank you!

You have the gift of teaching. Thank you.

Thanks for the video! I am a personal trainer trying to educate myself more! Thanks for the great visuals! I have a hard time just reading text books so your videos are perfect for me!

Thanks for the Video dude! This is very helpful! Keep up the good work.

@sueha62 You're very much welcome. Glad that you found value in the videos. Stay tuned for more :)

@letty3434 With regular exercise, one of the things that happens is that the heart gets more efficient at pumping blood. In other words, our Cardiac output increases. One of the ways of doing that is by decreasing End Systolic Volume. I talk about that in episode 50. Check it out and it should help you understand it.

I also want to say thank you soooo much for these amazing videos! It has made everything so clear! :) These videos are by far the easiest to understand for me :)

I do appreciate the clarity with which you explain each topic, your voice is calm and allows students to really understand what you are explaining, UNLIKE the professor that we got at City College :(

You are helping lots of people! No doubt. Sorry to bombard you with questions! Thanks for all the videos

I have been understanding biology, physiology and Anatomy from your videos! YOU ARE AWESOME.. thank you alot !!! :D

Thank you for sharing your knowledge with us.

THANK you these videos are incredibly helpful studying for my A&P class!

omg your such a blessing thank you soooooo much for these videos you do not know how much you've helped me with class. Will you be posting any videos on blood

my teacher never teach us how to calculate SV ,and i don't know these but i'm clear now. Thank you so much !!

you helped me pass my biology test! THANK YOU!

Such a helpful video and straightforward to the topic. Thank you soo much !

@jennyjunaRN You are very much welcome. Thank you so much for your feedback. Stay tuned for many more videos.

THANK YOU FOR THE EXPLAINATION, IT IS SO HELPFUL:

So just to make things clear, if EDV = 120mL and ESV = 50ml the stroke volume is 70mL. so 70mL of blood is pumped to the body when the ventricle (mainly referring to LV) contracts?

SO helpful!! Thank you so much!!

Thank you! Very clear & easy to understood.

Omg I finally understand . when my teacher tried to explain this the whole class was confused . Sometimes you just need to put things in simplified terms so students can understand without all the fancy jargin

Thank you So much ...You videos are so much to me

you are my lifeline!!!! you TEACH. my lecturers in school - they CANT TEACH. :) You're awesome! :) You have really helped me alot! I am a FAN!

Thank you. Great job.

Wonderful! Thank you so much!

Thank you... I'm a nursing student and this is very helpful!!!!

i'm lucky to find these videos because i'm in trouble with physiology ,,,thank you

OMG! THANK YOU SOOO MUCH! THIS HELPS OUT SO MUCH!!!

Awesome video. Thanks

@letty3434 This is another one for Episode 53. Cardiac output stays the same. That's because stroke volume increases and heart rate decreases. CO = SV * HR. They balance each other out. Check episode 53 for a more detailed explanation.

I love you and your videos!

I've been watching all your cardio videos today! really enjoying your clear and understandable explanations. thank you :) also, you remind me a bit of the Science Dude from Bones! haha

I'am dental student and I have learned a lot of yours episode , thanks man ♥

Textbook is always confusing. Thanks so much for this video... I just subscribed to your channel, thanks again.

Interactive Biology Can you please do a topic about afterload. I really love your videos and they have been helping me with my revision. I will be so happy if this can be explained . thanks

You are a life savior! ❤️

Thank you so much!!!

You are the bomb!!! I'm in Nursing school and this really helps me. I can be a better nurse because of you!

Thank you too much 👏🏼🌸

@letty3434 You should check out the video I uploaded today - Episode 53. That will help. The main idea is that with regular exercise, the heart gets better at ejecting blood from the heart. Everytime it beats, it send out MORE blood than in an untrained person. In other words, there will be LESS blood in the heart after it contracts. That is the End Systolic Volume and it is decreased. Once again, check out Episode 53.

Thank you very much

@TimmysMummy LOL, You are welcome, you are welcome, you are very much welcome. Glad you are enjoying it so much :D
