Which statement about systemic effects is false?

Which statement about systemic effects is false?

• A. Systemic effects are absorbed into and circulated throughout the body
• B. Systemic effects occur at sites other than the entry point
• C. Systemic effects can last a short or long time
• D. Systemic effects originate at the entry site and may spread

Answer: (D)

Systemic effects mean a substance is absorbed into the body and travels through the bloodstream to produce effects at distant sites, not just where exposure happened. The statement that is false says these effects originate at the entry site and may spread. In reality, after absorption, the effects aren’t confined to the entry point; they can affect tissues and organs throughout the body as the substance circulates. These systemic effects can last for a short or long time, depending on the chemical’s properties and how the body processes it. The other statements fit what systemic effects are: they are absorbed and circulated, they occur at sites away from the entry point, and their duration can vary.
