Answer:
The hormones involved in the calcium homeostasis are parathyroid hormone, cholecalciferol and calcitonin.
Explanation:
The maintenance of calcium level in the body is important for the proper functioning of body. The increased level of calcium is known as hypercalcemia and low level of calcium in body is known as hypocalcemia.
Hormones that regulate the level of calcium in blood are as follows:
Parathyroid hormone: The parathyroid hormone stimulate the calcium reabsorption in case of hypocalcemia. The osteoclast bone activity increases and calcium reabsorption from renal tubule, increases the calcium level of the body. This maintains calcium homeostasis in the body.
Calcitonin: An increase in the calcium ion concentration stimulates the secretion of calcitonin. The calcitonin hormone inhibits the osteoclast bone reabsorption, decreases the blood level in the body.
Cholecalciferol: This is also known as vitamin D metabolites. This hormone is stimulated in case of low calcium levels. The calcium level can be increased in the body by increasing the phosphate and calcium absorption from the gastro intestinal tract.
