Question

If one kidney of a man is lost, the other kidney enlarges to take over the function of the missing kidney. This is called

• A. Restorative regeneration
• B. Reparative regeneration
• C. Autotomy
• D. Compensatory hypertrophy

Answer 1

The correct option is D Compensatory hypertrophy

When there is an increase in the size of an organ or tissue and it has to perform additional work of the damaged or paired organ, then it is called compensatory hypertrophy. Here, one of the kidney is lost and the other kidney increases the size to take upon the work of the lost kidney. So, this is perfect example of compensatory hypertrophy.

Thus, the correct answer is option D, 'Compensatory hypertrophy'.
