Some people are born to teach well and this guy, for me, is one of those people. I watched a lot of videos explaining this and never had a better grasp of it until now.

2 hours of lecture I learnt nothing compared to only 10mins spent on this thank you Dr you are saving lives

[koli_pee]

Two hours of lecture is nothing compared to this 10mins of video...you made it look so easy...thank you Dr John campbell🙌🏾

[IAMCHIDERA]

I watched you 4 years ago and you were the best foundation to my medical school journey
I’m so grateful
I have remembered your drawing for literal years

Basic structure and function of the heart. Often people gloss over the 'simple' stuff, and miss areas of important understanding. The main things are the plain things, and often, the plain things are the main things. Please draw your own diagram, rather that taking the short cut of freeze faming and screen capture.

I am one person who is not into medical information but after watching this i felt love for this subject developing. I could see passion for his work in his eyes everytime he looked back at the camera as if addressing a class. So much respect to you Dr

[elytrapug]

All my biology teacher does is ask us to look through textbooks every single lesson and do the bare minimum of teaching. I've learned more in this video than I have in two weeks worth of lessons regarding the heart. Thank you Dr.

[ellecaballero]

Absolutely phenomenal !!! 👏👏👏
There is so much to be said for simplicity and thoroughness. When you can take such a difficult subject and break it down so well, you are indeed a pedagogue.
Thank you, thank you, thank you. 🙏

[niph]

You're simply a genius! You explained in 10 minutes what my professor couldn't do in 50!

[NURSEASMAH]

I shouldn't have to spend over two hours reading books to write my exams. I am a nursing student and this video has made my day. Thank you doctor

[benedictusanastasis]

The best lecture ever melts down all confusions. May God bless you more with happiness and prosperity Dr. C you are a gift to the world.

[Doctor-to-beee]

It's nine years ago, but never got old by its elegance, Thanks Dr!

[gracetalatala]

I have never been so thankful with today's technology that I have access to this kind of lecture. Watching you feels like I am in a highly sophisticated school. Learnings never made so easy. Thank you so much, Sir! Godbless!

[vincentromero]

i just spent 20 mins and I learned so much more than listening to 3 hour lecture from my other class...thank you Dr. Campbell for your easy to understand heart anatomy

[BrittanyJanelle]

Thank you so much! I'm in nursing school and struggling with the cardiovascular system, this video helped me understand the structure and function of the cardiovascular system.

I'm currently on orientation on a CICU unit and was just about to quit when I stumbled upon this video. OMG!! Everything makes sense to me now due to this lecture. And I love the way you took your time in explaining everything, I've been playing this video over and over again. Thank You Dr. Campbell!!!

Hello Dr Campbell. I am an expat living in California and currently about to sit the California State exam for my EMT (emergency medical technician) course. It is an accelerated course and a brain overload. I search and watch many you tube videos during my text rest period to provide additional mental stimulus to assist in memory imprinting. It works for me. One thing on youtube that is difficult is finding reliable, consistent videos that cover the exact information that I need and present it in a very memorable way. I have watched the three videos on the heart. They are excellent. I must commend you on your instructional techniques as they are proving invaluable for me. Thankyou so much. I will be looking for other videos that you post. I have a lot of learning to do. keep up the GREAT work and thank you.

[ljude]

These lectures is how I understood the structure of the heart and in turn scored an 86.2 on my Cardio A and P exam.
Thank you, sir

[nomatterwhatguys]

I worked in cardiac post surgery service in France (réanimation cardiaque = ICU) during 25 years before suspension ! Thanks for your class, it made me happy to hear it in your own language i love!

[zgyybul]

I feel more educated on this in just these few minutes unlike the one week I spent in class learning this... Thank you Doc 🙏
