Studying for my EMT exam and the flow of blood in the heart only clicked when watching your video. Thanks for the excellent video.

[@LauzaLoistl]

After watching 10 videos on this topic, THIS VIDEO just clicked. So clear and understandable. Thank you so much 🙏

[@brittanylewis7027]

Exact same

[@SiebertScience]

You're welcome! Thanks for the kind comment!

[@tolasaraji6474]

Hello my sister

[@tolasaraji6474]

​@@brittanylewis7027 ❤

[@Itswillfraser]

Same here, wish me luck for my exam..

[@GuyMortensen1962]

This guy is a natural teacher, informative, nicely paced, good reinforcement (with analogies or aide memoire suggestions) and all without becoming an ego trip. I hope he benefits from his generous use of time and knowledge. I am grateful and impressed. Guy Mortensen

[@SiebertScience]

Thanks, Guy!

[@nebretfeysa6484]

For the first I ever understood how the heart really works. God bless you bro.🙏🙏🙏

[@bettekavalec1454]

BEST, most UNDERSTANDABLE video on this subject that I’ve ever seen!!!

[@becscan]

Clear, concise, and understandable WITH an uncomplicated diagram which he labels AS HE GOES, eliminating confusion and ensuring that the viewer does not feel overwhelmed.

[@frielboniepe642]

The explanation is very clear and precise

[@lark3414]

The heart is an amazing organ I can't believe all of this happens in seconds. So important to care for yourself

[@LenoreGrogan]

absolutely one of the best lectures I have heard. His humor as well as when he repeats and recaps is awesome and makes it easier to understand

[@12peekabooo]

You know why I immediately subscribed to this channel? Because after decades as a cardiac patient trying (and usually failing) to grasp how the blood flows to and from the heart, this guy just gave me a simple tutorial in ten minutes that makes everything crystal clear. If his other videos are half as good as this one, I’ve got a lot of watching ahead of me! Thank you!

[@heartbrokenamerican2195]

He makes the concept so clear and easy to understand

[@valdemirpelegrinello7149]

Very clear explanation. Clear voice and clear talking. Very clear diagram and labels. This is helpful video. Thank you so much.

[@becscan]

I HIGHLY RECOMMEND THIS VIDEO!!! Thank you so much for making this video!!! It strips away all the unnecessary information AND includes the important details- like what the coronary arteries do, what is/causes a heart attack, the flow of blood through the heart AND BODY WITH o2 and co2, the major vessels attached to the heart and their functions, and what makes the “lub” and “dub” sounds that we hear! I also really appreciate that you gave the opportunity to go through it on our own with *AND WITHOUT* the labels! That was extremely helpful and gave me a ton more confidence that I understood and could accurately explain the material! I honestly can’t recommend this video highly enough for people struggling to understand the path of blood and oxygen through the heart, lungs, and body!

[@tpfrmpv8351]

Honestly, I have to say that I am tremendously grateful & appreciative for this informative explanation of the heart... within 30 minutes I've already mastered the understanding and labeling of the heart. thank u Sir.

[@user-fn3he9xq6t]

Best video on the internet by far.

[@susanbassey-duke4487]

The most concise and well articulated presentation on the topic. Thank you 🙏

[@padmapriyas3556]

I have my exams in a few days I just couldn't understand this topic I have been searching the internet for very long time and found your video. Thanks dude I am literally crying. Thank you sooooooo much. You just gained a new subscriber 💖

[@johnnycashm0ney307]

I could never wrap my head around how the heart works after reading so many texts and watching so many videos.... I needed this. You go into detail with every aspect of the heart and how they all function and function together. I will definitely be rewatching this because the heart is just something that I have a terrible time understanding.

[@intrepid_sagacity_motivation]

This video was the only one from which i understood EVERYTHING very EASILY

[@chinesegamingv3462]

man you deserve the best teacher award seriously, you made it super easy. thank you sooo much sir.

[@ams1978]

Thank you so much! I've been studying for my A&P test for weeks and it wasn't clicking until I watched this video. The drawing and labeling are EXCELLENT!

[@Lizzy-ct5tn]

Thank you very much!! Just watching the video for the 11 minutes really helped me understand more clearly Definitely will use this to study. Thank you for your time and videos.

[@alocinttarp5907]

Your teaching on point. Amazing❤

[@supadrew94]

YOU MADE THIS LOOK SO EASY!!

[@dansunsomeil]

Thank you so much for this! Like another commenter, I am suffering through an accelerated summer anatomy course with about half a day dedicated to learning everything about each topic, and this is the first resource I’ve found that has made me finally grasp the blood flow through the heart!

[@LIEJAY]

studying for simulation exams, thank you for this video, excellent explanation and so clear to understand.

[@euc5619]

I love the way he teaches us.🥰

[@jacobj.mendoza1093]

Bro Literally you’re the best one! Watch many videos and this one was the one

[@africahomeremedies8722]

There's no way after listening to his teachings you will not understand , because he speaks very clearly , not so fast and he keep repeating the topic over and over again for poor brain like me who can't grab easily. So very happy i found you. and i must subcribe right away. Thanks for having peoples interest at heart.

[@Cocodanon]

Thank you soooo much!! This really helped 😃😃

[@netchill5772]

Thank you so much! I have tried learning this in the past (for other classes) and nothing has ever made sense till I watched this video!!🙌🏼🙌🏼

[@MvpChacha]

Such an amazing video. Very clear and I was able to understand everything you discussed. Thank you !!

[@DenysB.]

Decided to refresh the structure of the heart. So not everyone is given this way to present knowledge. My respect and thanks. 👍🏻

[@eunicema17]

Very helpful, short and sweat, very cleared!

[@user-zp6ce7vq4b]

This is so helpful, Thank you!! I'm in a summer AP2 class and it only gives us about 2-3 days to learn stuff like this. I understood it so clearly from you.

[@user-zu2sm9rs2p]

I am taking A&P in my class and I Love the way you explained it.! Clear and simple. You know what you are teaching about. Continue sharing with us with your teaching style!

[@X4Y_Me]

It's way clearer than any other video thanks so much

[@eddies5675]

[@stephanieskarr426]

You made this make so much sense. Now I understand it better. Thank you ❤️🙏

[@Antoine-Zim]

I’m preparing my NASM personal trainer certification. That’s so helpful, easy to digest and clear. Thanks for sharing

[@dorathyalbert9849]

Thank you so much! You repeating the circle again,made it easier for me to understand it better. I really have a blocked head when it comes to cvs, and I am so happy that this makes me got a clearer grip of the whole thing. And am gonna use this as a powerful tool to imagine and get better. Thank you so much! Watching from 🇳🇬

[@neilwilliams5823]

This is an excellent, easy-to-understand, concise explanation and diagram of how the heart works.

[@emillyluciano9604]

This has to be THE BEST video explaining systemic and pulmonary circulation thank you so much!

[@Preciselylate322]

THIS video helped me so much!!!! I followed along on my own whiteboard. Copied your drawing and started labeling and writing out the process. Took me like an hour with all the pausing BUT by the end of the video, I was able to recite the process and name the parts without looking!!! THANK YOU! ❤🎉

[@user-ty5fo4io5k]

Im so glad I found your channel. You’re so informative and this has really helped me understand AP.

[@andrewduggan8584]

Thank you for this very informative video. Clear, concise, and detailed. This helped so much!

[@user-vp1su3mo6p]

This was a total game changer, reading how it works and then watching this gave it the clarity I needed. Thank YOU!!

[@flyingcolors980]

Nursing Faculty here. I commented on your kidney vid a while ago. I adore your work on this one too. I've shared w colleagues, it's essential our RN students understand this topic, as it influences chf, mi, and valvular disease. Students give great feedback as well. I have them study this video in preparation for a quiz their first day back from midterm break (yeah, I'm mean lol) and they do so well after watching your videos. Wish I had your vids 20 years ago when I got my degree in biology... Those chemistries nearly killed me! 😂 Best wishes and thank you again.

[@jacquesviau6165]

Ty. Sir, I am an Accountant about to retire. Learning this for personal knowledge. And I must say you are a Natural. I finally comprehend the cardio respiratory system Cheers from Montreal

[@thumperliciouz]

Best explanation on KZbin! Thank you!

[@bouchrarachid3653]

Thank you so much Sir. You are a true teacher. God bless you.

[@Sara-md8nu]

This took me forever to figure out. I slid by on physiology exams but once I started nursing school I absolutely had to understand it as well as all of the medications and their mechanism of action on the heart. Anyways I graduate in 2 weeks with my BSN and just landed a job on a cardiac unit. ❤❤❤

[@rockjock1965]

So simple and well presented thank you

[@johngray7317]

Great video ,very comprehensible and informative. Thank you.

[@jeremywheeler2122]

Thank you for explaining this slowly like I'm 5 years old. I needed that! I've been watching a number of videos on the heart due to phlebotomy school and my desire to become a EKG technician later. Yours is the only one that's clicked so far.

[@23DoPeE]

This was a big help quick and to the point. Thank you!

[@zacharyhamisi9482]

You made the concept of heart anatomy look easy. Thank you so much!

Ok, you are amazing. Better than the textbook, and honestly, better than the way my professor explained it.

[@DocGero]

Excellent and simple explanation.

[@victoriambewe5246]

Thank you, this was really helpful

[@karenquinn7638]

You are the best describing the structures and functions of the heart. I now know the heart has separate functions and structures, also, I now know how the blood travels through our arteries and veins. Thanks! I hope you teach about the structures and functions of the whole body. Thanks again Karen.

[@SiebertScience]

Thanks, Karen! I'm working on making videos on more parts of the body, but it takes a long time do make them...I'll get there eventually!
