White blood Cells-What are they???
Before you recieve a full explaination of what white blood cells do, you need to know that the body has two main ways of protecting itself from disease.The first is passive immunity. this system trys to stop pathogens (which are not actually diseases but the cause of diseasses.) from getting into the body!!! The bodys basic passive immunity system includes the mucus cilia and skin,from the respiratory system, and the stomach acid and emzynes in tears. the second defence against diseases is called active immunity. This is where the white blood cells come into place,as the white blood cells are one of the major functions in this system.
What Three Main Things Do White Blood Cells Do To Defend Against Disease???
*The white blood cells ingest pathogens and then destroy them.
*They also create antiboddies to destroy the pathogens
* they also create antitoxins to neutralise the toxins produced by pathogens
Antibodies and antitoxins are not real things they are speacalist protiens
The white blood cells do not eat the pathogens,they ingest them
PATHOGENS ARE NOT DISESE ITSELF, BUT THE CAUSES OF DISESE.
