Question

Suppose a person is being chased by a dog. Decide which hormones would be released in the person’s body and Outline what their effects would be on the body

Answer 1

When you are chased by a dog there are many chemicals which are released. The easy way to think about this is what does your body need to happen to stay alive and healthy?

1) Your body needs to move information quickly between brain and body. Adrenaline allows this.

2) Your body need to be able to maintain a state of high blood pressure to escape. Noradrenaline does this.

Together, these two hormones are known as catecholamines.
