The effector of a feedback mechanism is usually which part of the body?

A) skin

B) brain

C) gland

D) stomach

B) brain

Explanation:

Feedback mechanisms are actions capable of controlling the body's homeostasis (balance).

The brain has the main role in these processes, promoting antagonistic actions, dividing into positive and negative feedbacks, such as the increase or decrease in body temperature or blood glucose level, for example.

Positive feedbacks act to amplify actions that promote changes in the body, while negative feedback acts to reverse changes that have occurred. These are more common than the positive ones.

Your answer is B) Brain
