immune system
Internal disease fighters
The immune system is the body's defense network against infection and disease.
It includes white blood cells, antibodies, lymph nodes, and other organs and tissues that identify and destroy harmful invaders like bacteria, viruses, and cancer cells.
A weakened or compromised immune system leaves the body vulnerable.
Autoimmune disorders occur when the immune system mistakenly attacks healthy tissue.
