Reference: AQA
The sequence runs from adrenaline release to increased heart rate, then to faster delivery of oxygen and glucose, and finally to more energy available in the brain and muscles.
In humans, the processes of reproduction are controlled by hormones, and changes in one hormone affect the release of others through feedback.
Hormones such as thyroxine and adrenaline help the body respond to change, maintain stable internal conditions and enable rapid responses.
A gland detects a change and secretes a chemical messenger that affects distant target organs.
