I've been confused with this concept for years, but you concluded everything! Thank you so much!

Glad it was helpful!

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 :)

i don't why i looked for this video in the middle of the night for no reason , but i m glad that i understand it :')

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.

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

Extremely helpful. Thanks a lot.

You X-ray image just killed me.

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

FOR SERIOUS STUDENTS, IT'S BEST VIDEO!

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

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

Very understanding video . nice presentation

This helped a great deal, thank you.

great presentation just like a meditation.....

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

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 :)

Really good explanation, thank you! :D

You're a brilliant teacher

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

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

Surprisingly helpful.

Yay I got it! THANK YOU SO MUCH!

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

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

Explanation is very inspiring an intelligible.

amazing work buddy

ASMR warning -- kH

Thank you for the great video!

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

thanks to you I understand how it works now

best explanation. Straight forward !

Great video. Thanks!

thank you for this explanation!

Very helpful explanation, thank you!!!!

Thank you so much! You are an angel!

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!

he is spitting facts in this video

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

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.

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

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

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 👍

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

Thanks sir. very helpful video

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 video

Savage

helped so much! Thanks :D

Understood it better than before

Great explanation! :)

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

the teachers voice is different.

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

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

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

thanks, this really helped!

I'm Satisfied! 😇

Oh my god the whisper came into my headphones at the beginning and it scared meeee why does the voice sound likke that

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

Ur a bio teaching god

This 8ne was helpful.......I understood it!!!!😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁

Nice video 🐠

thank you!

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

0:45 What an xray

Is it changing molecular H2O or is there 02 gas in the water

@CraigSavageScience

There is dissolved O2 in the water

thank you so mcuh!!!

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

very nice!

good job!

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

Excellent

Thank you for explaining so well.

Good

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.

I live your voice.

you are my superhero

Knowing the answer is one thing, understanding the answer is other -craig savage

Brilliant video! do you have a email if I have any questions?

thank sir i understand this vedio

thanks!

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 have my zoology final tomorrow and this really helped :)

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!

Thank you! Very helpful!

So confused still, thanks though.

but sir you didnt talk about the process of ruardation which is the most important mechanism in fishes.

So dats how gills work. Cool.

great video, thanks for putting this together

Can we make artificial gills ?

really helpful, thank you!

How does gill filter out bacteria and toxic chemicals

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.
