Explanation / Answer

Role of calcitrol as below:

Calcitrol is the steroidal enzyme or bioactive form of vitamin D produced for the maintenance of serum calcium and phosphorus.

In digestive system:

It directly acts to enhances the calcium absorption from the intestines when there is hypocalcemia( low serum calcium levels I.e.10mh/dl).

In Urinary system:

it increases the reabsorption of calcium from the renal tubules which helps to increase the serum calcium in cases of hypocalcemia and decreases calcium loss in urine.

skeletal system:-

main function of the calcitriol is bone resorption. The hormone acts as osteoblast which turns to cause calcium to be moved out of the bone into serum to increase serum calcium.

Endocrine system:-

It is concert with the parathyroid hormone. Calcitriol and parathyroid hormone together collaborate to maintain normal serum calcium.

Cardiovascular system:-

As the calcium is the essential cation for muscle excitability, calcitriol makes availability of calcium for cardiac muscles.

Integumentory system:-

Calcitriol is useful for autoimmune diseases of skin like psoriasis. It maintain healthy skin structure.
