Keeping healthy - The body's different defences against infection, white blood cells, immune system, helpful 'medications' as well as harmful substances

Explaining the body's ways of fighting infectious diseases, immune system, detecting and treating diseases e.g. vaccination-immunisation, new drugs, antibiotics, monoclonal antibodies, disease tests

 Doc Brown's GCSE level biology revision notes

This section helps you answer questions like ... How does our body defend itself when it becomes infected?   What are the physical and chemical methods of protection?   What is a pathogen?   What is our immune system?  What is a vaccine?  How does vaccination-immunisation protect us? How are new drugs to treat and protect us developed?


Sub-index for this section on our body's defence mechanisms

(1) A historic note on cleanliness! What types of dangers exist? Types of pathogens

(2) Our body's physical defences against pathogens-infectious diseases

(3) Our body's chemical defences against pathogens infectious diseases (excluding immune system)

(4) A Introduction to the body's immune system

(5) White blood cells and the action of phagocytes in our immune system

(6) The lymphatic system, lymphocytes - formation of antibodies in our immune system

(7) The action of memory lymphocytes and production of anti-toxins in our immune system

(8) Vaccination-Immunisation - including MMR - 'pros' and 'cons' of vaccination

(9) Drugs - introduction to medicines to treat disease and developing new drugs

(10) Using antibiotics to kill or inhibit the growth of bacterial pathogens

(11) Using antiseptics and antivirals to combat pathogens

(12) Monoclonal antibodies - production and uses

(13) Tests and methods for detecting diseases

Keeping healthy - communicable diseases - pathogen infections

Keeping healthy - non-communicable diseases - risk factors for e.g. cancers
