Regulatory Mechanisms

Slide subtitle or context (optional)...

●
PTH stimulates calcium release from bones and increases calcium absorption in the gut
●
Calcitonin decreases calcium release from bones and increases calcium excretion in the urine

●
Vitamin D increases calcium absorption in the gut
●
Calcium and phosphate levels are regulated by a complex interplay of hormones and other factors
