In remodeling, what happens to the capillary arcade and collagen?

• A. Capillary arcade collapses, collagen is restructured
• B. Capillary arcade expands, collagen continues to increase
• C. Capillary arcade remains, collagen degrades
• D. Capillary arcade forms anew, collagen is degraded

Answer: (A)

In remodeling, the tissue shifts from a vascular, loosely organized matrix to a stronger, more organized structure. The capillary arcade tends to regress as edema resolves and the need for a dense vascular network decreases. At the same time, collagen fibers are reorganized and cross-linked, transforming the initial, relatively disorganized matrix into thicker, aligned fibers that provide greater tensile strength. This combination—capillary regression with collagen restructuring—best fits the described outcome. Capillary expansion or new formation, ongoing collagen increase, or collagen degradation do not match the remodeling process.
