During remodeling, which process occurs?

• A. Capillary arcade collapses, collagen is restructured
• B. Fibroblast activity increases
• C. New blood vessels form rapidly
• D. Inflammation intensifies

Answer: (A)

Remodeling in wound healing is when the scar tissue matures: collagen is realigned and cross-linked to increase tensile strength, and the vascular network regresses as the tissue becomes less vascular. The process described—capillary arcade collapsing as the capillaries regress and collagen being restructured—fits this maturation phase. In contrast, increased fibroblast activity, rapid formation of new blood vessels, or escalating inflammation are hallmarks of earlier phases (proliferative or inflammatory) rather than remodeling. So this description best captures what happens as the tissue remodels and strengthens over time.
