The term for the effect of substances on the body or an organ is called what?

• A. Response
• B. Toxicity
• C. Hazard
• D. Efficacy

Answer: (A)

Response describes how the body or an organ reacts when a substance interacts with it. This term covers the observed changes in function or physiology caused by the substance, whether therapeutic or not. Toxicity refers specifically to harmful effects at higher exposures, hazard is about the potential to cause harm in a given situation, and efficacy is about the ability to produce the intended therapeutic effect. Since the question asks for the general effect on the body, the broad idea of a reaction or response best fits.
