Endocrine System

Question 1

What does the thyroid gland release and what do they do?

Answer 1

T3 and T4 - released in response to cold, exercise, malnutrition, sleep, stress and low plasma glucose levels - they increase metabolism and heat production

Calcitonin - released due to increased calcium levels - decreases amount of calcium re absorbed from kidney

Question 2

What does the thyroid gland release and what do they do?

Answer 2

Adrenaline + noradrenaline - fight or flight - increases HR, dilates vessels of essential organs, constricts less essential, increases metabolic rate + dilates pupils

Corticosteroids - long term stress hormone

Glucocorticoids - increases metabolism, suppresses inflammatory and immune responses

Mineralocorticosteroids - maintains water balance and electrolyte balance
