Physiology Of Calcium And Phosphate Regulation

A number of hormones interact to regulate the Ca2+ and phosphate concentrations. The most important are PTH and 1,25-dihydroxyvitamin D (1,25-(OH)2D; calcitriol), which regulate mineral homeostasis by effects on the kidney, intestine, and bone (Figure 61-3).

Parathyroid Hormone

PTH is a polypeptide hormone that regulates plasma Ca2+ by affecting bone formation/resorption, renal Ca2+ excretion/reabsorption, and calcitriol synthesis (thereby indirectly regulating GI calcium absorption).

The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
