Learn and talk about Immune system, Organ systems

The immune system refers to all of the cells, tissues, organs and processes that protect an organism from invasion by pathogens. Viruses, bacteria, parasites, and some toxins are some of pathogens that the immune system is involved in eliminating from the body.
