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.
Which gland secretes a hormone that regulates blood calcium levels? The parathyroid gland secretes parathyroid hormone (PTH) which is responsible for monitoring blood calcium levels by mobilizing calcium reserves in the bone, increasing intestâ¦inal absorption and increasing renal excretion. Another hormone involved in regulated Ca blood levels is calcitonin, secreted by the thyroid gland.
