Type of repair where damaged cells are replaced with simpler cells?

• A. Replacement
• B. Reconstitution
• C. Regeneration
• D. Remodeling

Answer: (A)

In repair, there are two main outcomes: regeneration, where the original cells and tissue structure are restored, and replacement, where the damaged tissue is substituted with a simpler form, typically scar tissue made of fibrous connective tissue. This substitution results in tissue that is present but less complex and usually with reduced function compared to the original. So, when damaged cells are replaced with simpler cells, the process described is replacement. Regeneration would aim to recreate the exact same cells, remodeling refers to the maturation and reorganization of scar tissue rather than a substitution with simpler cells, and reconstitution isn’t the standard term used for this repair pattern.
