The Correct Option is B

Solution and Explanation

Parathyroid hormone increases the Ca2+ levels in the blood. PTH acts on bones and stimulates the process of bone resorption (dissolution/ demineralisation). PTH also stimulates reabsorption of Ca2+ by the renal tubules and increases Ca2+ absorption from the digested food. PTH is a hypercalcemic hormone and along with TCT (thyrocalcitonin), it plays a significant role in calcium balance in the body.

Human Endocrine System

The human endocrine system is a messenger system that balances or controls distant target organs through feedback loops of hormones released by the internal glands of an organism right into the circulatory system. The hypothalamus is the neural control node for all endocrine systems, in invertebrates.

Functions of the Human Endocrine System are:

The endocrine system controls a variety of body functions through hormone release. Hormones are built by the endocrine system's glands and pass throughout the bloodstream to various organs and tissues in the body. Hormones then command these organs and tissues about how to act.

The Endocrine System is in charge of the following bodily functions:

  1. Metabolic rate
  2. Development and growth of a human being
  3. Reproduction and sexual function
  4. Heart Rate
  5. Blood pressure
  6. The appetite is the need to eat
  7. Controls cycles of sleep and wakefulness
  8. Controls the temperature of the body
