Question

Correctly identify the following situation as an example of positive OR

negative feed back. When blood pressure increases, signals are sent to the
brain from the blood vessels. Signals are sent to the heart from the brain,
and heart rate slows down, thus helping blood pressure to return to
normal. *

1.Positive Feedback
2.Negative Feedback

Answer 1

Negative Feedback

Step-by-step explanation:

Positive feedback is only used to enhance the stimulus. In this case, the blood pressure was sent back to homeostatic levels which means that the stimulus was reversed in order to reach dynamic equilibrium.
