Which term means derived from outside the body?

• A. Internal
• B. Exogenous
• C. Intrinsic
• D. Endogenous

Answer: (B)

Exogenous describes origin from outside the body. It refers to substances, factors, or agents that come from the external environment or are introduced from outside, such as medications given to a patient or toxins encountered externally. In contrast, endogenous or intrinsic terms refer to something produced within the body, and internal is a less precise way to express within-origin. Because the question focuses on something derived from outside the body, exogenous is the best fit.
