- Increases heart rate
- Reduces blood pressure
-
In which situation is adrenaline produced by the adrenal glands?
- Low blood sugar
- Digesting a meal
- Sleep or rest
- Fear or stress
-
Which process is directly stimulated by the hormone thyroxine?
- Water reabsorption
- Glycogen breakdown
- Heart rate speed
- Basal metabolic rate
-
Besides metabolic rate, what processes does thyroxine play an important role in?
- Growth and development

-
A person is startled by a loud noise. Which hormone's effects prepare the body for fight or flight?
- Oestrogen
- FSH
- Adrenaline
- Thyroxine
-
What does adrenaline boost delivery of to the brain and active muscles?
- Thyroxine and insulin
- Carbon dioxide
- Oxygen and glucose
- Water and urea
-
Thyroxine levels are controlled by which process?
- Active transport
- Negative feedback

-
A rise in a hormone reduces the signal that causes its release. This is an example of:

- Enzyme inhibition
- Negative feedback
- Positive feedback
-
What is the primary function of a negative feedback control system?

- Amplifies a change
- Reverses a change
-
Which response does adrenaline prepare the human body for during stressful situations?

- Growth and division
- Sleep and repair
- Fight or flight
-
Which gland releases the hormone adrenaline during times of fear or stress?
- Adrenal gland
- Pancreas
- Thyroid gland
- Pituitary gland
-
Which gland produces and releases the hormone thyroxine into the bloodstream?
- Pancreas
- Thyroid gland
- Adrenal gland
- Pituitary gland
-
How are thyroxine levels in the human body controlled?
- Blood pressure
- Negative feedback
- Positive feedback
- Nerve impulses
-
What happens when a body condition monitored by negative feedback rises above normal?
- System reduces it
- System increases it
- System stops working
- Condition stays high
-
A person's basal metabolic rate increases. Which hormone is most likely responsible?
- Thyroxine
- Progesterone
- Insulin
- Adrenaline
-
What term describes a system that returns body conditions back to a set point?

- Glucagon
- Adrenaline
- Thyroxine
- Oxytocin
