Question

Quizplus · Accepted Answer

Parathyroid hormone is the most important regulator of Ca2+ concentration in plasma as it increases Ca2+ reabsorption from the bones and kidneys while enhancing active vitamin D synthesis in the kidney, which increases Ca2+ absorption in the gut. The other hormones listed may play a role in regulating fluid and electrolyte balance, but they do not have as significant an impact on Ca2+ concentration in plasma.
