Very clear and concise. Saves you hours of reading convoluted textbook descriptions. Good job.

Excellent Video. Thanks for posting it. The drawing makes everything much easier to understand the basic physiology of liver

Your videos are great! Im a pathology resident and these were great reviews of hepatic physiology and micro anatomy! Thank you for sharing!

I cannot thank you enough for a very simple, easy-to-follow, and engaging presentation. This really helped me out! Thank you so much!

I'm a pharmacy student from the UK. Your videos are awesome! You focus on little bits at a time and bring them all together after we understand to allow us to appreciate the bigger picture!

I'm an M1 who tried going through Boron, Ganong's and Netter's before watching this video series... I find that it's now much easier to understand those texts with the context your videos have provided. Thanks a lot!

Another fantastic video, that takes a complex subject and breaks it down to an easily understandable format.

Another excellent video providing a succinct understanding of liver histology and physiology, thanks again Andrew

Great video!

yooo your the bomb better than my two textbooks thank you from the bottom of my heart. your helping me prepare for my Physician Assistant exam it means the world to me. God bless you who help thousands conquer physiology!!!!!!! 😘

Again, a wonderful explanation building upon the other two hepatic physiology videos! Your illustrations are very helpful in comprehending the functions of each area and the cells associated with them. Always enjoy watching your videos...thank you for your knowledge and time!

Thank you for these great videos! They are some of my favorite physiology videos I've seen on KZfaq because every concept is thoroughly drawn out and not glossed over with a fancier power point presentation.

Thanks for these videos Andrew. It's nice for me to review at night when I'm tired of reading and doing flashcards.

thanks, a lot easier than the 3 hours i spent reading my a&p textbook chapter!

You are an amazing teacher. Your speaking speed is perfect so i don't have to pause to write stuff down which is great. You also don't waste time talking about irrelevant things like other channels do. The level of info isn't overwhelming at all and its very informative and just what i need to study for my med school finals.. ahh thank you so much i owe you my lifeeee

great video and very simple..thanx for ur great effort

Very clear, excellent. Thank you again !!!!!

u just made hepatology simple!!! great job!

Perfect video, perfect pace too, allowed me to take note while you were explaining... Thank you so much!

thank you andrew. I am an SRNA and you are a great web professor!

Thank you so much Andrew, It was great lecture and very helpful to me to understand the cells consist in liver. Once again thank you !!!

thank you. very informative and well presented

watching from Kenya ....thank you so much dr. Andrew

Thank you for the informative videos. Its been a while since I as studied the hepatic system so I think I'll need to go through these a couple of times. :)

great guide to understanding this. I never could grasp what a sinusoid was until I saw this.

This was so helpful, thank you so much.

Fantastic!!

Awesome video. One thing to include. The cholangiocytes are also present in the gallbladder. Histologically they appear as simple columnar epithelium cells. I subscribed btw :)

as with your other videos, really good explanations made it easy to understand!

Andrew Is an unbelievable teacher!

Thanks so much! You make it so easy to understand ;)

I can't thank you enough for teaching this one; I want to learn more b/c of it. thank you!

Thanks for this video, finally I understand it! :)

Thank you so much! Very helpful!

u r doing really a gud job, i really like ur videos, it gives deeply knowlwdge and simple for understanding.. . thnkss again

This was very very helpful! thank you!!

Thankyou! From New Zealand :)

Thank you Andrew. I didnt get it from the book Best and Taylor. I was desperate. Have a good day sir!

Hi Andrew, thanks for the video - I enjoy the clarity you bring to the complicated liver. I will always remember what fenestrated means now that you gave the background on the root meaning. Question: What modifies blood composition? Is it Hepatocytes or the actual sinusoids?

Oh man, you are awesome!

Thank you 🙏🏽🙏🏽🙏🏽

very good lecture i really benefited.

I loved the video! Thank you! In the first video you discussed three functions of the liver. Would consider producing a fourth video that categorizes the cells by their proscribed functions and go into more detail on the process of the function and implications of cell failure? Also, when one has a fatty liver, where are the fat cells located and how do they interrupt liver functions?

hey! great videos!! thank you!! where can i find the next lecture? (about sinusoids) you say in your video that you are going to talk seperatly about the sinusids.. can you please add a link to this vodeo? thank you (i am looking for the histopathology of cirrosis and portal htn) again THANK YOU

lovely presentation

Hi Andrew, great video! The one thing I'm curious about is the short discussion on the hepatic zones. They are typically described using the schematic of the hepatic acinus, formed by drawing a diamond between two adjacent central veins and two adjacent portal triads/hepatic arteries. The Zones are then made by slicing the diamond, with Zone 3 being nearest the diamond points and Zone 1 nearest the bisector of the diamond. Using this schematic, it seems that drawing concentric circles around the Central Vein would better approximate the zones than circles around the Portal Triad, as you have drawn and described. Let me know what you think.

👍👍👍, thumbs up triad.

really...everything was perfect

This was great! Would you be telling me about the start of fatty liver and where in your diagrams this would happen?

thank you :)

Hello:), great video! I have one question please: why Cholangiocytes are involved in being a part of the livers structure (rather then a structure of bile ducts). How do they contribute to the liver if we exclued bile ducts, gallblather and the "green part"? Also what are the Pit cells? There is very little information about those and they are also included as a cells of the liver Thank you

great video for review! thank you Sir! if could give more thumbs up i would - wonder who are the sad handful that gave a thumbs down?

Thanks for the excellent video. Since there is good evidence that bilirubin functions as a strong antioxidant, what is the mechanism for inflammation when bilirubin levels rise intrahepatically during cholestasis?

Weather the RBCs are destroyed in liver? if yest then how? and by which cell in liver?

Great video, andrew, thanks. I am currently doing fish kidney histology for fish feed to test for toxicity, can you do a video about that , thx.

What hepatic dysfunction results in Primary Biliary Cholangitis and Primary Sclearosing Cholangitis?

I don't see your video which further explains portal hypertension more indepth than the short portal circulation video. Do you have one?

How exactly is this tissue layered? Do these lobules run perpendicular to the surface or horizontally? Are there any other structures (microscopic) besides lobules? Otherwise very elucidating video trilogy....thanks!

How to stimulate sluggish Cholangiocytes?

would you be please make a vidio about liver function tests? Thanks in advance

Can you tell me the exactly how the RBCs are destroyed heptocytes?

where's the LFT?

i want subtitle; it would be very helpful if you have subtitles

Xcellent!yo drawing is congested,may you please redraw Nkqubela,frm south Africa

it was all clear thank you alot :) but....... you are too slow, so much wasted time, i recommend faster speech!!!
