Question

Quizplus · Accepted Answer

When blood calcium is high, the thyroid gland would stimulate the decreased uptake of calcium from food by the intestine and its secretion into the urine by the kidney. This is achieved by decreasing the production and secretion of parathyroid hormone (PTH) by the parathyroid gland, which in turn reduces the reabsorption of calcium from the urine and prevents its release from bones. Lower levels of PTH also reduce the activity of vitamin D, which enhances the absorption of calcium from the intestine. Therefore, the net effect is a decrease in blood calcium levels.
