You and your microbes – a TEDEd lesson from Jessica Green & Karen Guilleman.

11.1 Antibody Production & Vaccination

Defense Against Infectious Disease (AHL) from Stephen Taylor – thank you Mr T (of iBiology) –  from the OLD syllabus, much is still relevant.

Fantastic animated tutorials from McGraw Hill Education – the Immune response, T-cell dependent antigens, Epitopes, antigen-presenting cells & T-helper cells, cytotoxic T-cells & monoclonal antibody selection.

Three videos from TED-Ed: how we conquered the deadly smallpox virus (well, if we ignore the work of the WHO); Learning from smallpox: how to eradicate a disease and here’s a simple answer to How do vaccines work?

6.3 Defence against Infectious Disease

Thanks to Mr Taylor (of iBiology) for the powerpoint – from the OLD syllabus but some great stuff.

Fantastic animated tutorials from McGraw Hill Education – HIV replication (how a retrovirus replicates) & how the HIV infection cycle works – and an animated, narrated tutorial on the life cycle of HIV which also includes a quiz (from Sinauer Associates). All in more detail than we need. Why it’s so hard to cure HIV/AIDS (a TED-Ed lesson).

Mr W sings I’m a Virus!:

In Crash Course Biology #32 – Your Immune System: Natural Born Killer, Hank tells us about the team of deadly ninja assassins that is tasked with protecting our bodies from all the bad guys that want to kill us – also known as our immune system.

B5.2 Transport in Humans

Mr Exham’s site has a fantastic section on Blood and Circulation: videos, animations, quizlets, worksheets – go here now!

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity. 

B5.2 Revision notes in downloadable word format and here are the key terms and some definitions: Key Terms B5.2.


GCSE Bitesize – Blood Circulation covers how the heart circulates blood & the composition of blood (6m 35s).

Other videos include The Virtual Body – Circulation, Respiration & Breathing (19m), Science in Focus – Life Blood (19m 15s) & BBC Short Circuit Blood & Circulation (19m).

Various animations about heart & circulation problems can be found here.


Blood video (a 3m 44s lesson) & Blood music video by Peter Weatherall – 3m 3s and very catchy! And here is a day in the life of a Red Blood Cell (a one minute cartoon) & here a white blood cell chases a bacterium (20s).


Science Bank 22 (Body Parts): you just need Part 2 – the Heart (from 5m 20s to 10m 15s):


The Immune System is covered in the video The Virtual Body – the Immune System (19m), The Edward Jenner Story (a 2m 38s cartoon) & in this short video from The Virtual School:
