What term describes the result of a negative feedback mechanism?

• A. Amplification of the original stimulus
• B. Restoration of homeostasis
• C. Initiation of a positive reaction
• D. Permanent alteration of body function

Answer: (B)

The term that describes the result of a negative feedback mechanism is restoration of homeostasis. Negative feedback is a crucial physiological process that helps maintain stability within the body's internal environment. When a change occurs that disrupts homeostasis—like an increase in body temperature—negative feedback mechanisms are activated to counteract that change, bringing the system back to its optimal state. For instance, if body temperature rises, mechanisms such as sweating and increased blood flow to the skin help to cool the body down, effectively restoring the normal temperature range. This regulatory process ensures that fluctuations in various physiological parameters are corrected, keeping the body functioning optimally and within a narrow range of conditions, which is the essence of homeostasis.
