What is the main target organ affected by the hyposecretion of antidiuretic hormone (ADH) in diabetes insipidus?
Liver.
Kidneys.
Pancreas.
Heart.
The Correct Answer is B
The kidneys are the main target organ affected by the hyposecretion of antidiuretic hormone (ADH) in diabetes insipidus. ADH normally acts on the kidneys to promote water reabsorption and concentrate urine. In diabetes insipidus, the lack of ADH results in excessive urine production and dilute urine.
Incorrect choices:
a. This choice is incorrect. The liver is not the primary target organ affected by ADH in diabetes insipidus.
c. This choice is incorrect. The pancreas is not the primary target organ affected by ADH in diabetes insipidus.
d. This choice is incorrect. The heart is not the primary target organ affected by ADH in diabetes insipidus.
