Question : Name atleast two hormones which result in fluctuation of Ca

1.	Question : Name atleast two hormones which result in fluctuation of Ca^ (++) level.
Answer» Solution :Parathyroid and calcitonin are responsible hormones for the increased/decreased LEVEL of `Ca^ (++)`. Parathyroid increase `Ca^ (++)` in the blood which affects the bone and stimulates bone REABSORPTION. PTH stimulates reabsorption of `Ca^ (++)` by renal tubules and increase absorption of `Ca^ (++)` from digested food. Calcitonin is produced from peripheral cells of thyroid gland. It reduces `Ca^ (++)` level in the flood and produces ANTAGONISTIC EFFECT of PTH.
