The primary function of PTH is to help regulate serum calcium and phosphate. <\/strong>When ionized serum calcium decreases, PTH secretion increases. PTH indirectly promotes bone resorption, releasing calcium and phosphate from bone into the bloodstream. PTH stimulates the kidneys to convert vitamin D to calcitriol, its active form. Calcitriol increases intestinal absorption of calcium and phosphate. In the kidneys, PTH increases calcium reabsorption and decreases phosphate reabsorption. The decreased phosphate reabsorption increases phosphate excretion in the urine. Therefore, <strong>the overall effect of PTH is to raise serum calcium and generally lower serum phosphate.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Incorrect_Answer_Explanations\"><\/span>Incorrect Answer Explanations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A. \u201cParathyroid hormone decreases renal calcium reabsorption, causing the serum calcium level to fall.\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rationale: <\/strong>This statement is incorrect.
