Question

Quizplus · Accepted Answer

Feedforward mechanisms anticipate changes in regulated variables, such as internal body conditions, and make adjustments before the changes occur. The smell of rotten food triggering the vomit reflex is an example of a feedforward mechanism because the body anticipates the potential harm of ingesting spoiled food and acts to prevent it by inducing vomiting before the food is consumed.
