An example of the medulla of the adrenal glands working properly would be:
1. A child having an increase in heart rate and dilated pupils when scared.
2. A child relaxing and watching a video.
3. A child running a race with an increased respiratory rate.
4. A child having constricted pupils and a rapid heart rate after jumping rope.

Feedback
1. The medulla contains adrenaline, which controls the fight-or-flight response, which causes an increase in heart rate and dilated pupils.
2. Relaxation is not a primary concern for the adrenal medulla.
3. The race is a planned event and does not create more stress, requiring the release of the adrenaline response.
4. The pupils will dilate if the medulla requires an increase in the release of adrenaline.
