Increase in bleeding time and delay in blood coagulation is due to the deficiency of which hormone?
Parathormone
Parathormone, a hormone released by parathyroid glands, increases calcium level in the blood. Calcium plays a very important role in blood clotting. Therefore, deficiency of this hormone will decrease Ca2+ level in the blood, thus leading to a delay in blood clotting and increase in bleeding time.
