Transcript text: Which action is promoted by vasopressin?
Sodium reabsorption
Reabsorption of water
Tubular secretion of sodium
Red blood cell production
Solution
The answer is the second one: Reabsorption of water.
Explanation for each option:
Sodium reabsorption: This action is primarily promoted by aldosterone, not vasopressin.
Reabsorption of water: Vasopressin, also known as antidiuretic hormone (ADH), promotes the reabsorption of water in the kidneys, specifically in the collecting ducts.
Tubular secretion of sodium: This is not an action promoted by vasopressin. Tubular secretion of sodium is influenced by other factors, including aldosterone.
Red blood cell production: This process, known as erythropoiesis, is stimulated by erythropoietin, not vasopressin.
Summary:
Vasopressin promotes the reabsorption of water in the kidneys.
