A human kidney filters about 200 liters of blood each day. Approximately two liters of liquid and nutrient waste are excreted as urine. The remaining fluid and dissolved substances are reabsorbed and continue to circulate throughout the body. Antidiuretic hormone (ADH) is secreted in response to reduced plasma volume. ADH targets the collecting ducts in the kidney, stimulating the insertion of aquaporins into their plasma membranes and an increased reabsorption of water. If ADH secretion is inhibited, which of the following would initially result?

a) Number of aquaporins would increase in response to the inhibition of ADH.

b) The person would decrease oral water intake to compensate for the inhibition of ADH.

c) Blood filtration would increase to compensate for lack of aquaporins.

d) Person would produce a greater amount of dilute urine.

Cullen Erickson · Answer 1

The correct option is D. Person would produce a greater amount of dilute urine.

Explanation:

Antidiuretic hormone (ADH) can be described as a hormone that is produced by the hypothalamus part of the brain for the regulation of water. The amount of water that is reabsorbed by the collecting ducts is enhanced by this hormone. is also involved in increasing the amounts of aquaporins in the plasma membrane.

The absence of this hormone will cause less reabsorption of water. Hence, more amount of water would be released in the urine.
