[@angieeee8499]

Thank you so much for these videos!! They explain everything clearly and super quickly:)

[@libbypearson-qu2um]

I wouldn't be able to understand half of the biology content without your videos! Absolute lifesaver, thank you tonnes :)

[@cw2158]

This was so easy to understand! Thank you so much

[@archit-bhardwaj]

Thank you very much for these videos, they're extremely helpful!

[@charlie27203]

Perfect! Makes sense. Thanks

[@iforsyth2058]

are the surrounding cells muscle cells?? Thank you!!

[@BioRach]

Yes, muscle cells for insects to move/fly :)

[@sesomusic8602]

did you ever make a video on respiration in mammals because your way of explaining things makes them 10 x easier

[@BioRach]

Yes I have several videos breaking down the aerobic respiration pathway. Check out the playlist on my channel :)

[@shaai4227]

Hey bio rach could you please make 7.2 please

[@veisnthere9]

your videos are amazing thank you so much!

[@Ahshajahshaj]

Helloooo😊, I’m sitting my alevel independently and I’m really liking your videos. If I was to use just your videos to gain the knowledge part of biology do you think that would be sufficient? Thank you in advance and thank you for the videos 🤍

[@BioRach]

Hi there! Watching my videos will help with the knowledge bit for most of the content, but you'll have to do more learning on any topics that I haven't covered! I will be making more videos when I have time :) Best of luck!

Yes!

[@rangg4791]

quick question is ventilation and gas exchange the same thing

[@BioRach]

No they are different! Ventilation is the mechanical process of breathing, where your intercostal muscles, diaphragm and ribcage change your thorax volume abd pressure to either draw air into your lungs or to push them out. Gas exchange happens in the alveoli, where the oxygen and carbon dioxide move between the alveoli and the capillaries. A lot of people mix them up. Hope this clarifies it!
