Using an example of a hormone, outline the function of the endocrine system.

Which two of the following statements about the fight or flight response are FALSE ?

Shade two boxes only.

The fight or flight response involves:

A a decrease in the release of adrenaline.

B an increase in the rate of respiration.

What are hormones? Give an example of a hormone other than adrenaline and outline its function.

Xavier was cycling to school when he fell off his bike into the road. A teacher saw a car swerve, narrowly missing Xavier. The teacher checked Xavier was safe and asked him what had happened.

Xavier could hardly speak; his heart was pounding, and his mouth was dry. He felt sick and his hands were shaking. It took Xavier 20 minutes to feel calm again.

Outline the fight or flight response and use this to explain what Xavier was experiencing.

The adrenal gland is part of the endocrine system that produces adrenaline to help the body prepare for the fight or flight response.

Using an example of a gland and hormone, outline the function of the endocrine system. Do not use the adrenal gland/adrenaline as your example.

The fight or flight response enabled our ancestors to survive but can be less helpful in response to more modern stressors.

Explain how the body responds during fight or flight and why this could be unhelpful in a driving test situation.
