The answer to the first question is: calcitonin.

Explanation:

  • The C cells of the thyroid gland, also known as parafollicular cells, produce calcitonin. Calcitonin is a hormone that helps regulate calcium levels in the blood by lowering them when they are too high.

For the second question, the answer is: parathyroid hormone.

Explanation:

  • Parathyroid hormone (PTH) is the hormone that does the opposite of calcitonin. While calcitonin lowers blood calcium levels, PTH increases them by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and reducing calcium excretion in the kidneys.

For the third question, the answer is: testosterone.

Explanation:

  • The interstitial cells of the testes, also known as Leydig cells, produce testosterone. Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues and secondary sexual characteristics. Inhibin, on the other hand, is produced by the Sertoli cells in the testes and plays a role in regulating the production of sperm and the secretion of follicle-stimulating hormone (FSH).
