Over the whole 5 years of doing biology, you’re the only videos I understand and love

I would just like to say that i have my first science gcse tommorow and your videos have helped my revsion so much you make everything clear and understandable with good and easy visuals and shorter videos so im not so overwhemed lol. Thank You!

you have been referenced in my essay. A true chad

these videos are so helpful. I don't know what id do without you!!!

THANKS SO MUCH !! I did bio paper one on tuesday and a big question on this came up Also, making flashcards from these videos is my main revision and thanks to you i felt so confident and i felt like i knew everything that came up!!!! Your videos are a lifesaver, especially since I'm a visual learner. :D

this is very similar to aqa cgp biology revision guide... sounds almost word for word...but it is quite useful anyway

they took the phrase "i gave you my heart" literally.....

thank you soooo much!! I have a biology mock tomorrow and these videos are a life saver for revision! (the mock is kinda important because it's our last one before actual exams in may ahh so that's why I'm revising a ton) I love your videos, I've watched them since year 9!!!

After I graduate I'm going to talk one whole hour about this channel. You helped me so much!!!

Really makes you think how skilled the doctors are to do perform these surgeries...

my man carrying my academic life

My biology teacher made us watch this instead of actually teaching us XD

Carrying my GCSEs!

you are so helpful my book has two pages of that and you did it in less than fiveinutes

great vid my dude

i love how short your videos are with sm context in

are these videos for higher or foundation - potentially both?, very useful video btw 😃

Can you make a video about the cardiac cycle (I think it will be helpful to a lot of people) thank you ♥

just want to point out this video needs a slight update, Pig Heart Transplants are now possible and the first one was successfully transplanted in early 2022, only minor and won't really affect the exam, but its just a cool scientific advance.

Biology paper 1 tomorrow I wouldn't have a chance of passing science without Cognito such a great channel thanks so much

I think I'll pass this final after watching this. Thanks a lot

whats the name of the valve at 2:59 i can’t understand what the name is :/

Is this AQA?????

at 4:19, it's temporary, not temorary

😭🙏

when you talk about how the heart gets less oxygen from coronary heart disease, does it also get less nutrients? Because you said that the coronary arteries give nutrients and oxygen to the heart. Please respond ASAP

Mmm yes rip my heart and give to you ❤️

Wait a second Does this mean that if you want to donate your heart you will get killed😱😱

the word "lipids" makes me feel sick

you spelt temporary wrong 4:30
