Type of Hormone Steroid derivative

Glands and tissue that secrete calcitriol Parathyroid gland

Function of the hormone Important for the absorption of calcium from the stomach and for the functioning of calcium in the body It regulates calcium levels in blood IT IS USED FOR PEOPLE WHO KINDNEYS OR PARATHYROID GLANDS THAT ARE NOT WORKING

Regulatory mechanism Calcitrol mechanism of action takes place through its specific receptors Calcium-sensing receptors and vitamin D receptors modify the receptors in a positive manner Promoting its action and demonstrating a cooperative effect between the two

Conditions of hyper- secretion Can be toxic to the body Can accumulate in arteries, joints, ligaments, can kill muscle cells causes arteriosclerosis, bone deformation and muscle cramps

Conditions of hypo-secretions Rickets in children Osteomalacia in adults
