How parathyroid hormone and calcitonin regulate calcium and phosphate levels in the body?

Parathyroid hormone (PTH) and calcitonin both play important roles in regulating calcium and phosphate levels in the body. PTH is a hormone produced by the parathyroid glands that increases the absorption of calcium from the gut, increases the mobilization of calcium from the bones, and increases the reabsorption of calcium from the kidneys. Calcitonin is a hormone released by the thyroid gland that inhibits the mobilization of calcium from the bones, increases the excretion of calcium from the kidneys, and decreases the absorption of calcium from the gut. By increasing or decreasing the production of these two hormones, the body is able to maintain calcium and phosphate levels within a healthy range.

How does parathyroid hormone regulate calcium and phosphate levels?

Parathyroid hormone (PTH) is a peptide hormone secreted by the parathyroid glands that regulates calcium and phosphate levels in the body. PTH works to increase calcium levels in the blood by increasing calcium absorption from the intestine, increasing calcium reabsorption from the bones, and decreasing calcium excretion from the kidneys. Additionally, PTH works to decrease phosphate levels by decreasing phosphate absorption from the intestine and increasing phosphate excretion from the kidneys. Thus, PTH helps to keep calcium and phosphate levels within a normal range, and dysregulation of PTH can lead to a variety of medical disorders.

How do parathyroid and calcitonin regulate calcium levels?

Parathyroid hormone (PTH) and calcitonin are both hormones that help to regulate calcium levels in the body. PTH is secreted by the parathyroid glands when calcium levels in the blood are too low, and it stimulates the bones to release calcium into the bloodstream. Calcitonin is released by the thyroid gland when calcium levels in the blood are too high, and it helps to absorb calcium from the bloodstream into the bones. Together, these hormones help to keep calcium levels within a healthy range.
