Negative feedback

From WikiMD's Medical Encyclopedia

(Redirected from Negative feedback loop)

Negative feedback is a fundamental concept in biology and engineering, where it refers to a mechanism or process that reduces or counteracts the effects of a system output. In other words, negative feedback works to stabilize a system and maintain it within certain limits.

Biology[edit]

In biology, negative feedback mechanisms are essential for maintaining homeostasis. These mechanisms work by reducing the output or activity of any organ or system (back to its normal range of functioning) that has become too high or too low. Examples of negative feedback in biology include the regulation of body temperature, blood glucose levels, and blood pressure.

Engineering[edit]

In engineering, negative feedback is used to stabilize a system and reduce the effects of unwanted changes. This is achieved by feeding back a portion of the system's output to reduce its subsequent output. Negative feedback is used in many systems, including electronic amplifiers, to stabilize the gain.
