Ans.

Calcium homeostasis is defined as the process of regulation calcium ion concentration in blood and interstitial fluid. Hormones that regulate calcium ion level in body are calcitonin and parathyroid hormone.

The calcitonin decreases the concentration of calcium ions in blood, while parathyroid hormone increases the calcium ions in blood. The calcitonin hormone is synthesized and secreted by thyroid gland, while parathyroid gland synthesizes and secrets parathyroid hormone.

Thus, 'removal of thyroid gland shows impaired calcium homeostasis due to absence of calcitonin hormone.'  

The study of glands is called endocrinology. There are different types of glands and these are exocrine glands and endocrine glands.

The correct answer is mentioned below.

What are glands?

The organs which help information of enzymes and hormones are called glands.

What is calcium homeostasis?

  • Calcium homeostasis is defined as the process of regulating calcium ion concentration in blood and interstitial fluid.
  • Hormones that regulate calcium ion levels in the body are calcitonin and parathyroid hormone.

According to the question,  Calcitonin decreases the concentration of calcium ions in the blood, while parathyroid hormone increases the calcium ions in the blood. The calcitonin hormone is synthesized and secreted by the thyroid gland, while the parathyroid gland synthesizes and secrets the parathyroid hormone.

Thus, 'removal of thyroid gland shows impaired calcium homeostasis due to absence of calcitonin hormone.'
