of calcium in the blood decreases, which the body is a complex hormonal
It tries to compensate with the help of a regulatory system:
Release of Parathyroid Hormone (PTH)
Released from the parathyroid glands, PTH stimulates mechanisms that inhibit the uptake of calcium in the bones, and increase the activity of decomposing osteoclasts.
Kidney calcium reabsorption
PTH increases the withdrawal of calcium in the kidneys, so less Ca2+ is excreted in the urine.
Activation of vitamin D
PTH increases the production of vitamin D (calcitriol) in the kidneys,
