Which of the following is true of positive feedback mechanisms?
The result or response enhances the original stimulus, and the response is accelerated.
Which of the following is an example of a feedback mechanism?
A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms. When the body's temperature rises above normal, the brain sends signals to various organs, including the skin, to release heat in the form of sweat.
Which is an example of a feedback mechanism quizlet?
A good example of a positive feedback system is child birth. During labor, a hormone called oxytocin is released that intensifies and speeds up contractions. The increase in contractions causes more oxytocin to be released and the cycle goes on until the baby is born.
Which of the following is are regulated by a negative feedback mechanism?
Negative feedback systems work to maintain relatively constant levels of output. For example, the body maintains its temperature, calorie consumption, blood pressure, pulse, and respiratory rate based on negative feedback loops.
