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
Hello there´s an error in the video, it should be spelled as haemoglobin, not haemaglobin at second 44. By the way I love this channel, it saved my time and you guys summarized the contents extremely well. Thanks cognito.
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
i really owe you so much because im missing out on alot of lessons cuz im sick and im sitting here watching ur vids:) (i also watched the gas exchange and lungs video they were awsome)
Diluted seawater contains almost the same concentration of minerals and trace elements as blood plasma, and its sodium content matches that of blood. It has been used successfully in animal tests as a blood transfusion substitute, but human trials are long overdue.
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!

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
I’ve been revising for over 2 hours now and this is the last video I have to watch I’m so glad 😭
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.
