Blood Ca²⁺ deficiency stimulates __________ secretion,which leads to __________. A) calcitonin;more urinary phosphate reabsorption B) calcitriol;more urinary phosphate excretion C) parathyroid hormone;increased osteoclast activity D) growth hormone;increased osteoblast activity E) thyroid hormone;less urinary calcium excretion

Question

Quizplus · Accepted Answer

Blood Ca²⁺ deficiency stimulates the secretion of parathyroid hormone, which leads to increased osteoclast activity. This results in the breakdown of bone tissue and release of calcium and phosphate into the bloodstream, while also promoting urinary calcium excretion to raise blood calcium levels.
