Man you should publish your drawing as pdf format so that we could print and hang it on our desk! please think about this!

Really, Armando. You always talk about the topics most of us students have the hardest time understanding. You are amazing and I am really grateful that you make these videos. It's making medschool much more enjoyable. Thank you a lot.

WOWWWWWWW Now THAT is an explanation, so simple, direct and easy to understand thank youu Prof.Armando God bless ur soul :"D

Great,, I wanna add that ..HFE gene protein product facilitates the binding of transferrin to its receptors ,,leading to increased storage ..meaning that the body senses that there's enough iron , so the liver starts to make hepcidin to inhibit the absorption of more iron... When HFE is mutated ,,,stores aren't filled properly , hepcidin isn't synthesized , reabsorption goes unrestricted and unregulated >>iron accumulates in blood>> then it deposits in tissues

this is so helpful!!! NOT EVEN MY PROFESSOR IS ABLE TO EXPLAIN THIS AS WELL AS YOU!! I am sure this will get me a good grade in CELL BIOLOGY.

Beautiful! I loved watching you draw-I didn't need all of the information for my physician assistant class, but I was mesmerized and watched almost the whole thing. Thank you!

Man i love you !! when i see your videos i feel relaxed because i will understand

This is awesome Armando Hasudungan. I'm super grateful that you take the time to make these videos!!!!!!! God bless you.

I have low iron and want to understand how it affects my body. I'm not even studying medicine and I found this really fascinating and accessible. Thank you.

Thank you! This was exactly the explanation I needed to sort through some confusing experimental iron measurements. In-depth enough that I see the complexity, but simple enough that I grasped the concept.

That looks by far the hardest thing you had to explain, and it surely took you a lot of time to summarize it and organize it. Thank you a lot. It's really a life saving video.

As I end my 2nd year of medical school, I have come to the conclusion that Armando is one of the best “total tutors” on KZfaq. On a one to one comparison, he’s better than Osmosis, which I also respect. Since Armando came before Osmosis, it seems that Osmo can only hope to replicate Armando. I’m super grateful for your channel, Armando.

I would say it's perfect, since clear explanations are given. Each n every single detail is clearly explain for better understanding. Love it. Thanks !!!!

Somehow you always have the exact amount of detail I need for my courses! Thank you so much :)

These are brilliant well elaborated presentation makes easy in studying medicine.

Handsdown my favorite medical videos. Much love!

simply perfect.wow . after so many lectures today its clear to me . thank s sir

this is so insanely good. thank you so much! you just summarized and clarified 56 pages of Guyton's physiology for me!!

Great video 😊 Doing my specializaton's paper work in hemochromatosis and this is so helpful,I passed my physiology exam long time ago, now it's going to be so much easier to review everything 👌

Thank you so much. The video helped me a lot!

This is really well done. Would be great if you could do one about transfusional iron overload.

love all your videos! your artwork and science knowledge is swoonworthy!!!

Fantastic. The visual element really helped. Thank you.

Thank you so much. This was a very informative and well explained video- it really helped out with my research project!

The video makes iron physiology so clear. Love u !!! That helps a lot !!!

Excellent explanation for medicos and especially integrated drawings. Hats off

I always crack up when you say "I hope that makes sense"

thnkuu soo much...DAT helped me a lot for my exams....

Awesome explanations 👏🏻👏🏻 I just like the way you draw to tell us clearly✨

I think this video is so good it makes me want to live and learn forever. Wow! Thank you, Armando!!

Thank you so muccchhhh!!! 😭😭 In 14 minutes, you have very clearly explained something my lecturer could not properly explain in 2 hours. She was so hung up on the every little of each receptor and biochemistry of each enzymes she forgot to explain the process and concept.

This was just amazing, less time, well explained with diagrams and easy to understand 😍😍you should be awarded a nobel prize for this 😀

I hadn't understood anything about Iron metabolism until I saw this video. Thank you so much for making it easier to learn and I hope you will improve this channel more in the future. From Vietnamese medical student

Thank you so much for making it simple. I really appreciate your effort.

Thank u so much for diagrammatical representation of this video its really helps us to understand easy way

Brilliant well done and illustrated. Thank you!

Thank you, your explanation and drawings make it very clear.

Thank you so much! This is amazing. Thanks for publishing this. You make it so easy to understnd

When we do iron studies, we measure ferritin and transferrin levels from the *serum*. However you describe ferritin as only being located in the liver. I wish you had explained what ferritin is doing in the bloodstream and its clinical correlation.

THANK you for you sincere hard work. Truly GRATEFUL : )

Iron is mainly recycled in the body via macrophages releasing iron from red blood cells. So infact we only need about 1-2mg supplement of dietary iron absorption daily to account for bleeding, and shedding of skin cells etc.

That's great. This makes everything easier to understand! Thanks a lot!

Thank you very much sir ! I really appreciate efforts you have put to make this amazing video.

God bless you , you are an amazing guy and tutor , and your effort is so much appreciated ♥️♥️

Wow!this is one of your best videos I swear

you are the best !! you are a great help in our medical studies thanx alot !!!

what a wonderful and detailed explanation, thank you

Wow this was amazing and helped me so much, thank you!!

Thank you you taught us best way we can understand this iron 💓

You are a genius....I am saying again, you are a true genius.....the way you explained is just made me speechless. Thanks a lot sir......

This inspires me. Thanks.

Thank you so much. That's really helpful .

You make great videos. I enjoy the explanations.

Thanks alot for clear presentation

Very simple and informative too

thank you !! i passed anatomy and physiology this semester cuz of you ❤️❤️❤️

It definitely helps me understand the relationship between ferritin and serum Fe! I am confused about some concepts in hematology, such as TIBC, transferrin and iron saturation. Really hope that someday you could post a video about them. Thanks!

Excellent presentation.

What an amazing explanation. Thanks!

Great drawings, great explanation! Thanks you!

Wonderful handwriting and Amazing teaching skills:)

I have just been diagnosed with Hereditary Hemochromatosis at the age of 44 and found this video very useful to help me understand what it is and how it affects me. I am now on the look out, to get involved in any research projects on Hereditary Hemochromatosis, if you or any of your followers know of any in the UK please let me know. Or do a video, many thanks.

Thanks again for your help

U made it really clear to me. Thanku

Thank you for your efforts.

[23012] Lee I was able to understand the iron absorption process better with the pictures and kind explanations in the video. Thank you.

Is it possible to get an over head shot of the entire page

Needed this for my biomed essay in UK 🇬🇧 cheers from across the pond
