we've been discussing this for 2 hours and read the books but still couldn't quite get it and then i came upon this video and 3 minutes was already as helpful! thank you :)
Thank you so much. No one could explain this that easily. I really admire you. Thanks once again. I really appreciate your help. Keep the good working.
Great vid -I've been looking for something like this, with illustration as it helps my understanding - Biology not being my best/fav courses. Just a layman looking for some info as I am trying to educate myself on autoimmune process that I am dealing with real life. Thanks for the work.
hi Alex . great video! question though: Once the B cell get activated, doesnt it differenciate into plasmocytes to produce immunoglobulines ( which are your antibodies) ?
So in the case of a vaccine, is that the process that the body would go thru in order to create immunity or at least partial immunity (in the case of the flu)? I say partial because it only covers 4 strains and in the event one gets exposed to the other type it might be partially effective. Would that whole process of creating antibodies possibly cause side effects from a vaccine because the body is recognizing foreign invaders?
you know the part where you say that the antigen is presented by the macrophage. Is this antigen found on the surface of the pathogen itself? or somewhere else?
probably a very late reply as you have already done your IB. You have correctly understood what he was saying and the antigens are presented on or by the pathogen/virus etc, which the the macrophage engulfs by phagocytosis/endocytosis and forming a vesicle and whatnot to take it inside and use enzymes like lysosome which come by vesicles and fuse and break down the pathogen. Having broken it down it displays the antigens which were on the outside body of the pathogen signally inactive helper-T-cells to become activated and to become attached to the antigen and so on and so forth activating B-cells which then divide and conquer by mitosis and use the antibodies which they have replicated to attach themselves to incoming pathogens/viruses instead of going through this whole and laborious process again which takes a few days. This outline is basically how immunisation works where you give a weakened version or a dead version of the virus/pathogen and the immune systems goes to play. I hope you did well in the IB
It's the best explanation ever on the internet... Highly recommended 😇For all my medico pals out there🙌
This is the best example yet and this is EXACTLY what I needed, thank you so much!!
Glad it was helpful!
seriously appreciate this!! thank you for making this so much easier than it seemed 10 minutes ago :-)
Didn't really understand this during my school days. This was broken down to the simplest form. I really appreciate. Thank u
Trying to learn and mix up all these things since 2 years....and now....I understand what's actually happens....❤️❤️❤️thxxx... love from India

Was VERY useful!! Thanks soo much
Thanks for stopping by.
I'm getting an A on my biology test now! Thanks
So easy to understand. Great illustration
so helpful man, thanks. could you include like how the v genes, j genes and d genes are involved
brilliant hahaha stimulating, engaging, very nice. Love it
Very very helpful thanks for making this video.
hi， thanks for the video. How covid-19 anti body also build within the same way?
My brain is now opened to the knowledge and understanding of thy immune system. I feel like albert einstien now🤣🤣🤣
Thank you very much, a very simplified and it is very easy to understand the diagram. Thank You very much the presentation was on SPOT!
this is a fire explanation
i loved the explanation, its best way to explain
How AMAZING our body is, the immune system is simply a wonder
Very useful amazing and helpful , God bless you

Coolest thing I ever seen, Thanks!
This is so cool!
Thanks alot 🙏...it's really helpful for us to better understanding of HLA
well this is awesome and easy to understand! thank you!

Yay for a Game of Thrones mention! :P
Be careful guys, there's a jump scare at 2:22
But what if there is no antibody on B cells?
when you explained it, why was it so simple? Great video ^_^
very good and very useful. Thank you very much
very clear explanation!
Extremely useful for our exam tomorrow! thank you :)
Usefull. Tnx
Where this clonal selection will occur and how the antibodies switched from igm to igG??
Thanks man! Very helpful :)

Very helpful
What if no b cell identifies a pathogen?
great video easy to understand thank you sir
you are absolutely amazing
Thnx for this amazing explaintion..!!
How many antibody production per minute in human body
Great video man
Like honestly
:)

Excellent!! So helpful, THANK YOU!
WOW!!! Awesome!
THANK YOU VERY MUCH!!!!
At 8:25 I think you mean clonal expansion?
It was useful for school😊
Awesome
thanks so much!!
Great vid.
Are B-cells lymphocytes???
B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype.
thnx.
Thank you so much!
Thanks for stopping by.
I can't understand what's the role of white blood cell and why macrophages engulf foreign particle if WBCs can do it
macrophages are phagocytes for all intents and purposes - it IS the WBC that engulfs the foreign pathogen
Thank you so muchhh
I love you Alex Lee
Thanks to vid upload
Hahahaha brilliant analogies
who comes here after M2017 biology HL IB exam?
no one
Those silly cartoons were actually useful.
