Question

Which of the following hormones plays an important role in osmoregulatory function of kidneys by increasing ${\text{Na}}^{+},{\text{K}}^{+}$ and ${\text{Cl}}^{-}$ reabsorption from filtrate?

• A. LH
• B. Oxytocin
• C. Vasopressin
• D. Aldosterone

Answer 1

The correct option is D Aldosterone

Aldosterone plays an important role in osmoregulatory function of kidneys by increasing ${\text{Na}}^{+},{\text{K}}^{+}$ and ${\text{Cl}}^{-}$ reabsorption from filtrate, thereby increasing the blood volume, restoring salt levels and blood pressure.

LH is luteinizing hormone produced by gonadotropic cells in the anterior pituitary gland.

Oxytocin hormone plays important role in reproduction, childbirth and period after childbirth.

Vasopressin is anti-diuretic hormone that plays important role in maintaining osmolality through water reabsorption.

So, the correct option is 'aldosterone'.
