A larger quantity of dilute urine is produced in diabetes insipidus. This disease is due to the deficiency of:
Correct answer: A. Antidiuretic Hormone
- A. Antidiuretic Hormone
- B. Aldosterone
- C. Thyroxine
- D. Cortisol
Explanation
Option A is correct.Diabetes insipidus is a condition characterized by the deficiency or dysfunction of antidiuretic hormone (ADH), also known as vasopressin. ADH is produced by the hypothalamus and released by the posterior pituitary gland. Its main function is to regulate water balance by increasing water reabsorption in the kidneys. In diabetes insipidus, the lack of ADH or the kidneys' inability to respond to it leads to the production of larger quantities of dilute urine.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
