Verified step by step guidance
1
Understand the role of each hormone listed in the options: Insulin, Antidiuretic hormone (ADH), Aldosterone, and Cortisol.
Recall that facultative water reabsorption refers to the process where the body adjusts the amount of water reabsorbed in the kidneys based on the body's hydration status.
Identify which hormone is responsible for regulating water balance in the body. This hormone acts on the kidneys to increase water reabsorption when the body needs to conserve water.
Recognize that Antidiuretic hormone (ADH), also known as vasopressin, is the hormone that increases the permeability of the kidney's collecting ducts to water, promoting water reabsorption.
Conclude that the hormone promoting facultative water reabsorption in the kidneys is Antidiuretic hormone (ADH).
