The Click4Biology pages are here: Core – – AHL
A separate post on HIV/AIDS will follow.
The Immune System – Phagocytosis and Clonal Selection
Here are some very clear clips for the immune responses to infection, starting with a really well done explanation of Burnet’s Nobel-winning clonal selection theory:
If you like that, check out some more of the videos from the Walter and Eliza Hall Institute of Medical Research.
Try this animation and quiz: McGraw Hill Online Centre
And another Nobel-winner, the cellular response from CancerResearch.org
Phagocytosis in action:
Neutrophil (phagocyte) chasing a bacterium:
The humoral, though not funny, response – from the LifeWire
How does the leukocyte know where to go? Chemotaxis – from Wisc-online
Once you’re sure of how it all works, can you narrate this medical animation?
And for another of the body’s defenses: Natural Killer Cells

Defense Against Infectious Disease megapost
Here we go, Standard Level and Higher Level in one big post:
As always, North Harris College has a great set of links to immunology animations.
Here’s the core, for everyone:
Antibiotic action from HHMI
Antibiotic resistance from Sumanas
Interferon, an antiviral medication from the University of Illinois
Simple animation from ccbmd.edu
Retro-style animation and explanation from CellsAlive.com
More detail (better for HL) from McGraw Hill
HIV & AIDS:
Have a go at the Rediscovering Biology online text and animations
Here’s an in-depth look at the HIV virus from rnceus.com
And a good look at the HIV life cycle from Sumanas
You should really read this article on social and economic impacts of HIV
The resources for HIV out there are prolific, so go find them if you’re still curious!
And to set your mind at ease, the best HIV website: www.avert.org
Additional Higher Level content:
Start off with some of these resources from Bio-Alive.com
Explanation and animation from HowStuffWorks and ADAM
And from the Indiana Haemophilia and Thrombosis Centre
The Specific Immune Response
Great introduction by RM Chute
This one from McGraw Hill is really clear (we don’t need the bit about cytotoxic cells), and CancerResearch.org have these animations about the cellular response and humoral response.
Here’s a nice one about the action of antibodies from edumedia (but you’ve got to pay), and a better one on the action of immunoglobulins (antibodies) from WHFreeman.
Here’s a simpe YouTube explanation:
Good animations from McGraw Hill and Sumanas.
And when you’re through all that, have a go at a Virtual ELISA test from HHMI
You might even feel like a pregnancy test.
Here’s House MD to knock some sense into you:
And on more serious note – the NHS has a very clear website with animations.
Girls might want to know more about the HPV Vaccination and its protection against cervical cancer.
And for more readers and in-depth stuff:
The Media’s MMR Hoax from BadScience.net is the perfect reader for discussion of the perceived dangers of the MMR jab. You could pair it with this video (edited by an anti-MMR activist).
Go for Rediscovering Biology’s Emerging Infectious Diseases online course.
