A patient has a decreased vasopressin synthesis that causes polyuria and as a result of it evident organism dehydratati-on. What is the mechanism of polyuria development?
Answer options
- Reduced tubular reabsorption of Na ions
- Acceleration of glomerular filtration
- Reduced tubular reabsorption of water
- Reduced glucose reabsorption
- Reduced tubular reabsorption of protein
Correct answer
Reduced tubular reabsorption of water
Explanation
Vasopressin causes low diuresis due to increased reabsorption of water leading to increased blood pressure. Hence its decrease will cause reduced tubular reabsorption of water leading to polyuria.
