An Overview of the Immune System : Navigating the Marvels Within

An overview of the immune system allows us to understand how we stay healthy and how we survive infection.  Humans are regularly exposed to viruses and bacteria as well as other pathogens.  Most people experience a cold or the flu at least a few times every year.  The recent Covid 19 pandemic illustrated how important our immunity is.  It also made us very aware that even a great immune system does not stop us from getting ill.  But the state of our immune system does determine how well we recover from these pesky and often dangerous invaders.
