An exogenous variable is a variable which is not affected by other variables. On the other hand a variable is said to be endogenous if its value is determined by other variables.

What is endogenous and exogenous disease?

Many illnesses are associated with an alteration of the immune system homeostasis due to a combination of factors, including exogenous bacterial insult, endogenous breakdown (e.g. development of a disease that results in immuno suppression), or an exogenous hit like surgery that simultaneously alters immune …
