The two types of tissue repair are?

• A. Regeneration and healing
• B. Reconstitution and replacement
• C. Maturation and remodeling
• D. Scar formation and resolution

Answer: (B)

The main idea is that tissue repair can happen in two broad ways: reconstitution of the original tissue or replacement with scar tissue. Reconstitution, also called regeneration, means the damaged tissue is rebuilt by the proliferation of the remaining cells of the same type, returning the architecture and function to normal when the supporting basement membrane and extracellular framework are intact. Replacement occurs when regeneration isn’t possible or sufficient, so fibroblasts deposit connective tissue and form scar tissue. The result preserves continuity of the tissue but often with altered structure and reduced function. Some tissues regenerate readily (like skin or liver), while others mainly repair by scar (such as cardiac muscle or central nervous tissue).
