Can you add the explanation of the different types of white blood cells such as lymphocytes and phagocytes?
The phagocytes are the white blood cells that change shape to engulf/consume pathogens via phagocytosis
There are different types of lymphocytes with different functions
Type b produce the antibodies and another type produce antitoxins to neutralise the toxins produced by the microorganisms
@@scarlettbevan7756 Thank you so much!
sure
"Honestly-Im Fine" hahhhahahahaha
I have 2 masters degrees, but I am watching this course as I intend to switch careers.
That is how good your videos are.
I wish you had A-level videos to follow on.
I’ve been revising for over 2 hours now and this is the last video I have to watch I’m so glad 😭
Can you do blood typing ? Like the A,B,AB,O thing
really professionally done and clear to understand. One little remark - the correct spelling is heamoglobin.
Hi, thanks for the comment. The UK spelling is 'haemoglobin' (which is what we use in the video), while USA spelling is 'hemoglobin'.
@@Cognitoedu Ha ha, even I wrote it wrongly, sorry, typo. I meant you have written it wrongly haemAglobin, the correct one is haemOglobin.
this is one of the only science videos i can understand
ur videos are litterally the best omg and so well animated :D can u try to make videos of more advanced topics in detail too as u make such great videos that are easy to undersatng thnxx
bro literally explains a topic in 4 mins that my teacher took 30 minutes to explain 😞🙏🏻
I really appreciate you thank you so much.

10 MINS BEFORE MY EXAM
Lol fr
Can i ask a general question? I know i wont need this information for the exam but im curious to know.
Since the blood does not flow like a river but in are veins and arteries, how does the platelets heal the wound? does it diffuse? or some other process?
Thank you!
So basically - the platelets will just be in the blood, and they'll bind to the wound as they float by. They'll be attracted by chemicals that are released from the wound, and there also will be receptors they can bind on to.
Hope that helps!
@@Cognitoedu oh that's well cool.
