Exogenous

Exogenous refers to an action or object coming from outside a system. It is the opposite of endogenous, something generated from within the system. In the context of biology and biochemistry, exogenous factors are those that come from outside an organism, such as drugs, environmental toxins, or even foods that may affect the organism.

Overview

Exogenous substances may have various effects on the body. They can be beneficial, such as when they are used in medicine to treat diseases, or they can be harmful, such as when they are pollutants or toxins. The body's response to exogenous substances is a major area of study in fields such as pharmacology, toxicology, and epidemiology.
