Born in Paris to a grocer, Claude Oscar Monet moved at the age of five to Le Havre, a seaside town in northern France. The ocean and rugged coastline of the region had a profound affect on him at an early age, and he would often run away from school to go for walks along the cliffs and beaches.
Parathyroid hormone serves to increase blood concentrations of calcium. Mechanistically, parathyroid hormone preserves blood calcium by several major effects: 1  Stimulates production of the biologically-active form of vitamin D within the kidney.  Facilitates mobilization of calcium and phosphate from bone.
Calcitonin is the other major hormone involved with calcium regulation. Parathyroid hormone (PTH), produced by the parathyroid gland, increases the level of calcium in the blo â¦ od. It usually accomplishes this by increasing the resorption rate (taking back) from bone.Calcitonin does the exact opposite and reduces calcium in the blood.arathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it. 2 people found this useful. Edit.
