Question

Hyposecretion of parathyroid hormone affects blood

• A. Iron concentration
• B. Calcium concentration
• C. Potassium concentration
• D. Sodium concentration

Answer 1

Answer: (B)

Calcium concentration

Parathyroid gland is present in the form of four small pouches which are embedded in the posterior surface of lobes of thyroid gland. This gland secretes parathormone which increases calcium reabsorption from the bones by dissolution and demineralisation and causes mobilisation of calcium in the blood. It is a hypercalcemic hormone.

Hence, parathyroid hormone or parathormone affects blood calcium level.

So, the correct answer is 'Calcium concentration'.
