Question

Quizplus · Accepted Answer

Parathyroid hormone is responsible for increasing calcium reabsorption from urine in the kidney and increasing calcium absorption in the small intestine. Calcitonin, on the other hand, decreases blood calcium levels by inhibiting calcium release from bone and increasing calcium excretion in the urine. Vitamin D and cholecalciferol are involved in the regulation of calcium absorption, but they do not directly affect calcium reabsorption in the kidney.
