What is the immune system? Immune system defends the body.
White blood cells (WBCs) are the most important partof this immune system.
WBCs fight and destroy bacteria, fungi and viruses
that may enter the body

How does HIV weaken the immune system?
HIV enters the body.
WBCs are attacked by HIV.
The virus multiplies inside WBCs and infects otherWBCs.
Infected WBCs are eventually destroyed.
Leads to a reduction in the number of WBCs.
Ultimately leads to greatly reduced immunity.
