Which term best describes effects that affect the entire body rather than just the site of contact?

Which term best describes effects that affect the entire body rather than just the site of contact?

• A. Systemic effects
• B. Local effects
• C. Idiosyncratic drug reaction
• D. Allergic reaction

Answer: (A)

Systemic effects describe effects that involve the whole body. When a substance is absorbed into the bloodstream and reaches multiple organs, it can produce widespread responses rather than staying confined to the initial site of contact. Local effects, by contrast, stay at the point of contact, such as skin irritation right where a cream was applied. An idiosyncratic drug reaction is an unusual, unpredictable response that isn’t tied to dose, and an allergic reaction is immune-mediated and can be either local or systemic, but the term that specifically captures whole-body involvement is systemic effects.
