Name any two hormones which control calcium balance in the body. How do they function antagonistic to each other

Please find below the solution to the asked query

Calcitonin secreted by thyroid gland and parathormone (PTH) produced by parathyroid gland are the two hormones that regulate calcium level in the body. 

Parathormone and calcitonin​ act antagonistically to regulate calcium level in the body. Parathormone increases the blood calcium level while the calcitonin reduces the calcium level in the body. 

PTH is a hypercalcemic hormone. It increases blood calcium levels by dissolution/demineralisation from bones, reabsorption of Ca2+ by renal tubules and Ca2+ absorption from digested food. 
Calcitonin reduces calcium level in blood by inhibition of dissolution/demineralisation​ of bone.

Hope this information will clear your doubts about the PTH and calcitonin.

parathyroid hormone (PTH), calcitonin, and 1,25-dihydroxyvitamin D [1,25(OH)2D3].
