Parathyroid hormone(PTH) increases the `Ca^(2+)` in the blood by
a.Bone resorption/dissolution/demineralisation
b.Reabsorption of `Ca^(2+)` by the renal tublules
c.Increasing `Ca^(2+)` absorption from the diggested food

Antagonist pair off hormone which regulate Ca^(+2) in blood are

Antagonist pair off hormone which regulate Ca^(+2) in blood are

Which increases the rate of Ca^(2+) absorption from gastrointestinal tract

Which increases the rate of Ca^(2+) absorption from gastrointestinal tract

Which increases the rate of Ca^(2+) absorption from gastrointestinal tract

Assertion :- PTH is a hypercalcemic hormone which increases blood Ca^(++) levels. Reason:- PTH acts on bones and stimulates reabsorption of bone or demineralisation. PTH also stimulate reabsorption of Ca^(++) by renal tubules.
