Answer to Question #88248 in Human Anatomy and Physiology for Amberly Collins

Question

Brian has been diagnosed with a hypersecretory tumor of the parathyroid gland. What hormone will be hypersecreted? Would a hypersecretory tumor produce more than,less than, or the same as the normal amount of this hormone? What ion does this hormone control? Will this ion be found in higher or lower concentration in the blood? Will the ion be found higher or lower concentration in the urine? what painful kidney complication may result as a consequence of this concentration of the ion in the urine?

Answer 1

A hypersecretory tumor of parathyroid gland leads to the hypersecretion of parathyroid hormone (PTH). The tumor will produce more than the normal amount of PTH. The hormone controls the concentration of calcium in the blood. PTH causes the release of calcium from bones increasing calcium concentration in the blood. As kidneys filter blood and excrete the excess of calcium from the blood, the concentration of calcium in the urine will increase in patients with parathyroid gland tumor. This process will lead to the formation of kidney stones associated with painful symptoms.
