Which term means originating from outside the body?

Explanation:
Originating from outside the body is captured by exogenous. The prefix exo- means outside, so exogenous factors come from external sources, such as an exogenous toxin or an external infection. Endogenous means produced within the body, arising from internal processes. Idiopathic describes a condition with an unknown cause, not specifically about origin. Hypoxia refers to a state of insufficient oxygen reaching tissues, which is about a physiological condition rather than origin. Therefore exogenous best fits the idea of origin from outside the body.
