Quizplus · Accepted Answer

When dietary calcium is unavailable, parathyroid hormone (PTH) is secreted to increase calcium levels in the blood by decreasing excretion through urine and increasing calcium release from bones. Vitamin D acts with PTH to increase the absorption of calcium in the gut and also increases the amount of calcium retained by the kidneys.
