2. Amount of thyroxine in the blood

Thyroxine LevelThyroxine level too
low
Pituitary gland secretes TSH
TSH stimulates thyroid to produce thyroxin
Thyroxine level increases
Thyroxine level too high
Pituitary gland stops TSH production
Thyroid decreases thyroxine production
Thyroxine level decreases
