blood calcium regulation

• RISING BLOOD CALCIUM LEVEL:

  • thyroid gland releases calcitonin
  • stimulates calcium deposition in the bones
  • homeostasis: 10mg of calcium per 100mL of blood
• FALLING BLOOD CALCIUM LEVEL:

  • parathyroid gland releases parathyroid hormone
  • stimulates calcium release from the bones
  • homeostasis: 10mg of calcium per 100 mL of blood
