Question

What is one way that calcitonin and parathyroid hormone maintain homeostasis?

Answer 1

Parathyroid hormone is secreted from parathyroid glands. Parathyroid hormone increases calcium levels in the blood when they are too low. Whereas as calcitonin is a hormone secreted by the parafollicular cells of the thyroid gland. It works antagonistically to the parathyroid hormone. This means that calcitonin reduces calcium levels in the blood when it is high. It is, therefore, the secretion of both calcitonin and parathyroid hormone is determined by the level of calcium in the blood.

Answer 2

Calcitonin is ahormone that is poduced in humans by the parafollicular cells (other wise known as c-cells) of the thyroid gland. Therefore, inhibition of the osteoclasts directly reuces the amount the amount of calcium released into the human blood. This is just a simple explanation so now all you have to do is understand what will happen when you combine calcitonin and parathyroid.
