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.
In addition to releasing thyroid hormone, the thyroid gland also releases a hormone called calcitonin, which helps to regulate calcium levels in the blood.Calcitonin helps to reduce the calcium levels in the blood, whereas parathyroid hormone helps to increase the blood calcium levels.o when there is an increase in the serum calcium levels, the thyroid gland will release calcitonin to help reduce these levels. When people think about malfunctioning of the thyroid gland, what usually comes to mind is the increase or decrease in thyroid hormone.
