Another mechanism causes the factor to …
WebNegative feedback is a key part of homeostasis. When there is a change in the body’s internal environment, it is detected by receptors and the body’s protective mechanisms work to return this change back to the set point (the point at which the condition is at its optimum). The body counters the change, and hence this is negative feedback.
