Exogenous means originating from outside the body. Which option expresses this meaning?

Explanation:
Originating from outside the body means exogenous. This term denotes factors that come from the external environment rather than from within the body's own tissues. It’s used to describe external sources like environmental toxins, external infections, or influences introduced from outside. In contrast, idiopathic means the cause is unknown; iatrogenic refers to harm caused by medical treatment; hypoxia describes a state of insufficient oxygen rather than a source of origin. If a cause comes from inside the body, you’d use endogenous. So the term that expresses the meaning of coming from outside is exogenous.
