Cognito, Khan Academy, Amoeba Sisters, and Free Science Lessons are 4 reasons why I am going to get an A from all 3 of my exams. You guys are legendary.
I literally thought I’d be failing every exam until I found your channel and my grades have ACTUALLY gotten higher ever since... thank you so much for such good explanations..you’re better than our teachers 👍🏻
I basically owe my three 9s in GCSE science to Cognito, Amoeba Sisters, Free Science Lessons, and Study Smart Science, but I never thought I'd watch another of their videos after my exams... Yet here I am doing my biology summer work, where we have to do GCSE exam questions as a recap before A-levels begin, and I suddenly find myself very confused with AQA topics that I never did, due to doing Edexcel. So once again I'm being saved by these videos despite having already done my GCSE exams.
I really love this channel, the only channel so far that I don't need to watch more than once to understand and remember. To be honest, this is way easier to understand compared to 1 or more hours of learning in class (for me). And I tend to find science hard..I wish they have all of the topics which I'm studying ..... thanks a lot😘
This was an excellent help for my upcoming test. This channel explains things easier and better than most of my teachers and the channel is underrated.
I love your videos. They explain every thing in detail. This videos are excellent whenever you want to recap about anything in a short time. It is helping me a lot during my exams
thank you, I understand this a lot better now, even though I made condensed notes from revision guides and websites, I couldn't wrap my head around it, but this vid hopefully allows me to understand digestion more.
Blud I've got 3 days for my IGCSE exams and I was thinking I am doomed but I'm glad I found this channel... now IGCSE feel like a piece of cake... tysm!
This is an amazing and very easy to understand video. I really like the diagrams. Thanks for taking out your time, in order to make this brilliant video :)
Thank you soo much sir now i am here cuz your lessons are very nice i understand all of your lectures easily i am from Pakistan so i have some language problem but i understand you thank you again sir
Thank you for this video! When the bile neutralises the acid from the stomach when all the food goes next to the duodenum what condition does it make? and since the small intestine makes all 3 types of enzymes, does that mean they all work at the same type of Ph conditions? If so, is it acidic or alkali conditions? Thank you!
Heya! The pH in the duodenum is slightly acidic still, but not very as the bile neutralises most of the stomach acid. Yep the enzymes from the pancreas can all work at around the same pH Hope that helps! :)
THIS VIDEO IS VERY HELPFULL THANK YOU SO MUCH CAMBRIDGE BOOOK 7 TOPIC ALL CORRECT ON THANK YOU SO MUCH VERY HELP FULL FOR US I AM JUST 12 AND I LEARNT ALOT IN EEASY WAY
notes if u need: Digestive system: - To function humans need energy, carbohydrates (starch and glucose), proteins and fats - Digestion breaks down food holding these so we can absorb it in our body cells - Physical breakdown and chemical breakdown (enzymes) - food...Mouth...physical...chewing -saliva (salivary glands)...amylase enzyme which breaks down carbohydrates - Next swallow ... Esophagus... Stomach... Contracts it's muscular walls in order to push the food around and mix ... Produces pepsin which breaks down protein... Produces hydrochloric acid which kills bacteria and provides the right environment for the pepsin to work - After around an hr in the stomach... Food squeezed to small intestine... Nutrients Absorbed to bloodstream...Produces enzymes to and digestion (the pancreas produces pancreatic juices into the small Intestines and also the gall blader which holds produced bile that's from the liver (alkaline) which neutralizes the acid from the stomach which makes it more ideal for the enzymes to function and it emulsifies fats - helps break but blobs of fat into tiny droplets ) - Once foods digested into lots of small pieces it's absorbed along the lining of the small intestine straight into the bloodstream ( lining of intestine is a exchange surface which has lots of Villi which increase the surface area of the small intestine which means digested food can be absorbed to bloodstream more quickly, also villi have only single layer of surface cells which means nutrients only diffuse a short distance
Don't forget to mention that the villi very good blood supply which increases the concentration gradient so the food molecules can be absorbed to the bloodstream more quicker 👍
me:not getting a thing of what the biology teacher is saying me thinking:i wish he was my teacher i wouldve passed all of my exams you explain really well thanks!!!
Hi Ash, that's true, thanks for that - but the primary role of the large intestine is to reabsorb water, which is why the GCSE course focuses on the idea that large intestine is for water reabsorption.
@@Cognitoedu indeed :) I watched at least 20 of your videos today, and I must say that they're very informative. Thanks for the content! I do the Cambridge IGCSE, and, though that curriculum is a little different than the videos here, I still find your videos helpful. Greetings from Egypt!
Ahhhhhhh yes! I had my first exam today for computer science and it was literally the most stressful thing I've experienced in my lifeeee. It's bilology tomorrow and m sooooo not prepared!!!! Good luck on your exam tho I hope it goes well 🤩
I haven tread all of the other comments to see if this has already been mentioned but the word "oesophagus" is spelt wrong at 1;24. you spelt it without the "e". Great video though. Love the channel

Thank you! I am home learning now! This really helped me!
Edit: YOU ARE GENIUS!!!!!!!!
i learn more from these videos in 6 minutes than i do from my biology teacher in two weeks
Thank you Cognito for making so much Biology, Chemistry, and Physics videos, they have helped me alot over my science tests, Keep it up!
Glad you like them! 🙌
truly underrated! I got a 21 [/30] in my biology test after watching your vids!
I mean, its's not even a B... But congrats on not failing i guess?
I got 132 on my last mocks - grade 8 🤩🤩🤩
@@charmanderfan6945Bruv shut up, Bio is a difficult subject. His new score is probably an improvement from before. Focus on yourself.

This is sadly underrated, but why?? This help me so damn much thankk you cognito

thank you so much for this! i have a test tommorow and this is really helping me understand :D

Thanks Mahnoor!! we really appreciate your support 😊

this is the best learning courses ever i have seen😉😉😉😉😉😉
got bio paper 1 in about 2 hours, thank you
bro this dude teaches me more shit in 6 mins than my teachers do in an hour
I love everything inside the video and that is a masterpieces, it saves my year exam also.
Great video. keep up the hard work.
you are a legend lifsaver thank you keep it up
Thx 😊 really like the way it’s presented
And can you explain the circulatory system
For IGCSE BOARD
1:27 oesophagus you mean??
I got an exam in 2 hours, so im glad this video is quick
Does the amylase just break down carbohydrates and similarly pepsin breaks down just proteins? Thank you
The idea of the lock and key hypothesis, so only a particular enzyme can bind to a particular molecule.
@@22techinfo Thank you +Hassans Tech
So helpful thank you!

I have a question what right enviorment do we need for the pepsin to work ?
idk :/
Abit late but I'm pretty sure the right environment is hydrochloric acid which the stomach produces
