Minimum calcium is needed in the; blood if the level falls too low calcium causes parathyroid glands to release more para hormone into the bones and this causes the bones to release the needed calcium. blood if the level of calcium increases too much causes parathyroid glands to release more para hormone into the blood and this causes the bones to release the needed calcium. bones if the level falls too low calcium causes parathyroid glands to release more para hormone into the blood and this causes the bones to release the needed calcium. blood if the level falls too low calcium causes parathyroid glands to release more para hormone into the blood and this causes the bones to release the needed calcium. blood if the level falls too low calcium causes parathyroid glands to release more into the blood and this causes the bones to release the needed calcium.
