Final answer:
A person who has a hypersecreting tumor of the parathyroid gland would exhibit demineralization of his bones and tend to form calcium-containing stones.
Step-by-step explanation:
A person who has a hypersecreting tumor of the parathyroid gland would exhibit demineralization of his bones and tend to form calcium-containing stones. Hyperparathyroidism, which is caused by an overproduction of parathyroid hormone, results in high serum calcium levels and low serum phosphate levels, leading to bone destruction and the formation of kidney stones.
