Question

Quizplus · Accepted Answer

Aldosterone functions to increase sodium reabsorption, which helps to maintain electrolyte balance and blood pressure. It is secreted by the adrenal cortex, not the posterior pituitary. Its production is primarily regulated by the renin-angiotensin system, not ACTH. Its presence does not increase potassium concentration in the blood, but rather promotes its excretion.
