Question

The lost portion of the liver is regenerated by

• A. Reparative regeneration
• B. Compensatory hypertrophy
• C. Heteromorphic regeneration
• D. None of the above

Answer 1

The correct option is B Compensatory hypertrophy

• The liver is the only internal organ that can regenerate itself.
• Hepatocytes are the liver cells that are responsible for the liver's ability to regenerate; they act as stem cells that can re-form liver tissue. The liver can regenerate after either surgical removal or after chemical injury. It is known that as little as 25% of the original liver mass can regenerate back to its full size.
• The lost portion of dissected liver regenerates by Compensatory hypertrophy i.e The growth which is a result of increased cell size.
• So, the correct answer is 'Compensatory hypertrophy'.
