Human Biology 1.4 Describe how humans respond to pathogens
Subject content
Make sure you have up-to-date course notes.
The topics that you may be assessed on:
- response mechanisms that:
- prevent entry of pathogens – skin, mucus, cilia, acid, sweat, blood clots
- deal with pathogens after entry – white blood cells (production sites, functioning), inflammatory response
- support immunity (natural, acquired, active, passive) – antibodies (production, functioning), role of the circulation system, role of the lymphatic system.
- symptoms of pathogenic invasion
- methods for reducing spread. These are limited to reducing spread within the human body only.
You will find a wealth of information about these topics on the following websites:
- NZ Food Safety Authority (NZFSA), which has data sheets for food pathogens in New Zealand.
- Understanding infectious diseases, which includes topics about the nature of infectious disease, types of microbes that cause infectious diseases, the occurrence of infectious diseases, host defences against infectious diseases, preventive measures against and treatment for diseases, and more.
