This video gives examples of negative feedback ( A feedback system has three basic parts: a receptor, a control center, and an effector.A receptor is a body structure such as a nerve ending or sensory receptor that monitors changes in a controlled condition and sends input, usually in the form of a nerve impulse or chemical signal, to a control center, which in the body is typically the brain.A control center sets the range of values within Because a + feedback system continually reinforces a change in a controlled condition, some event outside the system must shut it off. If the action of a positive feedback system is not stopped, it can "run away" and may even produce life-threatening conditions in the body. With this terminology in mind, homeostasis then can be described as the totality of the feedback loops and feedback cycles that the body incorporates to maintain a suitable functioning status.
