A) collecting tube
B) proximal convoluted tubules
C) distal convoluted tubules
D) all of the above
Correct Answer: C
Solution :
The vasopressin hormone, secreted by neurohypophysis of pituitary gland promotes the reabsorption of water from the distal convoluted tubules of nephrons, reducing excretion of water in urine (= diuresis). Hence, it is called antidiuretic hormone (ADH). Its release in blood is controlled by an osmoregulatory centre located in hypothalamus. Hyposecretion of ADH causes diabetes incipidus.
