omg so did I lol. I woke up at 3 am and for some reason asked myself do gills separate the oxygen from hydrogen? couldn't get back to sleep till I found out. writing this now I realize if you have a fish tank and don't circulate the water, putting more o2 in, the fish will suffocate despite there being of water. I'm 28 and it took me 2 hours to realize that smh.

I woke up this morning and my first thought was, "How do gills work?". Thanks for clarifying.

I love how thorough the explanation is, as well as how you get people to engage and understand the material. My teacher heart found this very satisfying :)

All these people understanding it and I'm sitting here before my 50% exam hella confused

Thank you from an old guy who has not completely understood this until now. Great work!

Extremely helpful. Thanks a lot.

This makes so much sense. Thank you! My textbook didn't explain it well at all.

Thank you for this! Im in Animal Physiology and my teacher tried giving us a similar example but his example confused me more.. You explained it very well!! Thanks again!

I have a tiny class of two 7th grade students... who are pretty sharp! This will be great for them!!! thanks very much!!!!

This really helped with my study for an upcoming test, thanks

i am so lucky to have found ur channel. Your videos are exactly what I was lookin for according to my syllabus and calibre, sometimes i become so obtuse in class, but ur videos make me realize m not a dimwit

You X-ray image just killed me.

great presentation just like a meditation.....

Well explained! Thanks for letting me understand the whole thing!

Very understanding video . nice presentation

This helped a great deal, thank you.

FOR SERIOUS STUDENTS, IT'S BEST VIDEO!

Really good explanation, thank you! :D

amazing explanation, very clear, cut and clean. This is a brilliant system, so impressed !

Omg thank you SO much. I have my animal physiology exam later and I know that water-breathing animals mostly use countercurrent but I didn't know the mechanism, until now. You're the best :)

You're a brilliant teacher

I usually do not exalt someone and this is Awesome video. Many thanks.

Great video! Exactly what i needed to know for my exam👍

Surprisingly helpful.

Yay I got it! THANK YOU SO MUCH!

best explanation. Straight forward !

Great information, thanks. I wonder if that gradient idea is also functional in itself, since energy never wants to stop.

great explanation i didnt understand the countercurrent bit but now i do!

Thnks for yor vids. Explained extremely well. I ve been subbed for about 2 months now. The cellular repiration and photosynthesis vids were where I started. They were spot on. Only neg I have for ur vids is the volume seems lower than most videos. Besides that they are awesome and very helpful.

Thank you for the great video!

Very helpful explanation, thank you!!!!

thanks to you I understand how it works now

thank you for this explanation!

i used this for a presetation and it worked out well !

Thank you so much! You are an angel!

Explanation is very inspiring an intelligible.

u explained this so well thank u! my teacher just said something about a fish and the gills and drew a crazy pic. very helpful!

Great video. Thanks!

amazing work buddy

Love your video.. but can fish gills be manufactured for human use?

wow you're voice is so soothing! Thanks for the well explained video.

Great video! I just had one question-does the carbon dioxide gradient work in the same countercurrent fashion as the oxygen gradient?

Nice video....I understood 👍

thanks this helped me with my science project what i will be doing is puting a fish in defferent water tempitures like cold and warm

You are a really good teacher! Could you maybe also do a video on countercurrent exchange in kidneys and for even heat in mammals? Thanks for the video! You really helped me out :)

Great explanation! :)

Woah! This helped me so much :) I will be having biology final with a whole gas exchange theme and this really helped, because i have to remember so many things and this was a little bit confusing to me :D My teacher would be mad if she knew that i understood this in English and couldn't understand it in my mother language ;DD

It also moves the blood with the highest oxygen level through the head/brain first.

8 year question: what are the membranes, enzymes, cells, etc. Used in the gills?

ASMR warning -- kH

Thanks sir. very helpful video

Understood it better than before

does the countner current exchange increase the amount of oxygen that is diffused into the blood?

Amazing Video! I have an exam tomorrow and needed a refresher and it served me well :D

One thing I don't quite get here. I don't see why the examples are that different with regards to the "final product". They are both resulting in 20ppm of oxygen diffusing into the vessels of the gills. With the concurrent flow surely diffusion is initially faster then slows as equilibrium is met compared with the slow and steady counter current system.

This helped me so much

Great video

Thanks, I woke up at 5 and had this random question

sir, in this video, you didnt explain as to how and by what mechanism is oxygen separated from the water inside the gills ????

Ur a bio teaching god

This was great! I was quite confused with concepts until I watched this video

I live your voice.

thanks, this really helped!

Nice video 🐠

Great video. I'd love to use it for my marine science class presentation. I also teach Human A&P and will look for your rete mirable and Loop of Henle videos!

he is spitting facts in this video

Thank you for explaining so well.

thank you!

thank you so mcuh!!!

thank sir i understand this vedio

please make a video of the structure of a gill

Why can't my teacher be as good as you!?!?!

you are my superhero

Can we make artificial gills ?

savage explanation

That's great sir. Superb..

nice vedio

0:45 What an xray

thanks!

I still don't understand why the water has only 80ppm O2 before the counter current blood even reached the water. Shouldn't the water still have 100ppm O2 before the blood came? Where did the 20ppm O2 go, when there was no contact with the blood before? I am not sure if someone understands what I mean. But if somebody does, I would appreciate an explanation.

I don’t get how the blood mixes with the water, it’s inside the vessel right?

@msredmond3420

The blood and water don't mix. The blood stays in the capillaries and absorbs oxygen from the water through the walls of the capillaries. It's a bit like the engine cooling system in your car radiator.

I thought that water goes in through the mouth and out through the slits at either side of the body.
