Answer:
D. ACTH
Explanation:
Under stress conditions, corticotrophs of anterior pituitary gland secrete adrenocorticotropic hormone (ACTH). This hormone is also known as corticotropin and serves to stimulate the adrenal cortex to secrete its hormones. The glucocorticoids (mainly cortisol) from adrenal cortex serve to increase protein breakdown (except in liver). Cortisol also stimulates gluconeogenesis (formation of glucose from substances other than carbohydrates and lipolysis.
Cortisol also raises blood pressure and enhances inflammation, depresses immune responses. Mineralocorticoids (aldosterone) from the adrenal cortex target kidneys to stimulate the resorption of sodium and thereby retention of water in the blood.
