Final answer:
A person with a hypersecreting tumor of the parathyroid gland would likely experience demineralization of their bones and the formation of calcium-containing kidney stones.
Step-by-step explanation:
A person who has a hypersecreting tumor of the parathyroid gland would probably exhibit demineralization of his bones and tend to form calcium containing kidney stones. Hyperparathyroidism, which is caused by an overproduction of parathyroid hormone, results in excessive calcium being removed from bones, leading to structural weakness and potential fractures. Additionally, high blood calcium levels can cause calcium deposits to collect in the kidneys, resulting in the formation of kidney stones.
