A Level Biology Revision "Blood Clotting and Inflammation"
Вставка
- Опубліковано 12 бер 2023
- You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at blood clotting and inflammation. First we explore the process that takes place during blood clotting, including the roles of platelets and the clotting factor thromboplastin. We then look at what happens during inflammation, in particular the roles of mast cells, histamine and cytokines.

I'm in year 11 and am currently just revising for my chemistry mocks. You, sir, are a Saint. Millions appreciate your work. Such short, concise, and informative videos are few and far between. Thank you for making science revision so easily accessible
why u revising a level vids for gcses
@@yeliz6930I wanna know how well they did 😂
So glad to see you in person again
Another banger as usual
Thank you for another great video ❤
Thanks so much 👍👍 absolute lifesaver
im still in my igcse but i just came here to say thank you for this new information
Hi Sir, is it alright if you make a Video about
A) Metals and their uses
B) Periodical table.
Thanks!
Hi, can u do A Level Biology Biodiversity thats a tough topic and u havent done it yet, is it possible?
Acid rain is back with another banger
Mr.Shaun do you plan to cover the entire AS chemistry and AS biology syllabus before the upcoming May/June exam series?
I've finished the AS Chemistry course (apart from maybe two extra videos) and I have the Immune system and biodiversity topics for Biology to do, so hopefully I'll have all that finished by May.
hello shaun at this stage of time for gcse science would you recommend learning the content and then doing topic questions on our weak topics and then do past papers?
Yes that's exactly what I would recommend. In that order.
@@Freesciencelessonsthank you!
Hello Shaun how do you have so much time to create those videos, great help nevertheless 👍
I stopped teaching in a school in 2019 so I now make videos full time. An A level video takes about ten hours to make.
@@Freesciencelessons Thanks for your time and effort it really helps 👍
What about your gcse videos sir how long do they take to make?
Hi sir, are you going to do videos on the a level physics course aswell? (for AQA)
I'm sorry but I have no plans to make A level Physics videos as I've never taught it.
@@Freesciencelessons :( no worries thank you for the help
Hi Sir, is this infectious diseases playlist complete?
Hi. Sorry for the late reply. It's almost complete but I will probably add a couple more videos on specific diseases.
Hi shaun, do we need to know this for AQA ?
It's not on the AQA spec. The thumbnail of the A level videos has the exam boards that it applies to.
i love you
first🙀🙀🙀
