Question
In a person the tubule part of the nephron is not functioning at all. What will its effect be on urine formation?A. The urine will not be formed.B. Quality and quantity of urine is unaffected.C. Urine is more concentrated.D. Urine is more diluted.
Solution
The nephron is the functional unit of the kidney, responsible for the actual filtration and removal of wastes. Its tubule part is particularly important for the reabsorption of water and certain useful substances such as glucose and ions.
If the tubule part of the nephron is not functioning at all, it means that the reabsorption process is impaired. This would result in a large amount of water, glucose, and ions being lost in the urine that would normally be reabsorbed back into the bloodstream.
Therefore, the urine will be more diluted because of the excess water. So, the correct answer is D. Urine is more diluted.
