“Think of the immune system like the military, each part has a different role"
The first line of defense is the white blood cells, who are first to recognise pathogens and fight off infection. Lymphocytes, a specific type of white blood cell, work to allow the body to remember the invading microbes to fight them faster in future infections.
Other parts of the immune system include the bone marrow, where white blood cells are produced; lymph nodes, which produce and store infection-fighting cells throughout the body; and the spleen, which helps control and clean the amount of blood in the body.
