WebNegative feedback maintains homeostasis. Negative feedback mechanisms are so common in the body that we have a special symbol for them in the book-- a teeter-totter. Every negative feedback mechanism attempts to hold some variable-- for example, body temperature-- as close to a certain value as possible. This value is called the set point. … WebIn a negative feedback loop, feedback serves to reduce an excessive response and keep a variable within the normal range..
