Primary & Secondary Non-specific Immune Responses, defence mechanisms. A-Level biology (OCR & AQA)

This resource contains all the material you need to deliver the following two lessons:

5.1 Animal defences against disease (primary non-specific defence)
5.2 Phagocytosis (secondary non-specific defence)

Provided is a variety of activities, designed for either the OCR or AQA A-level specifications, to achieve the following learning objectives:

1. Recall the main defence mechanisms of the body (Grade C)
2. Describe how neutrophils phagocytose pathogens (Grade B)
3. Evaluate how antigenic variation affects the body’s response to infection (Grade A)

All the answers/mark shemes are integrated within the PowerPoint but in addition I have provided some of the activities (and mark schemes) as separate files for ease of printing if you prefer to print from .pdf files rather than .ppt files.

I am sure it will save you loads of time (because it took me a crazy amount of time to create it) and I welcome your feedback on this resource!
