During remodeling what is happening?

During remodeling what is happening?

• A. Capillary arcade collapses, collagen is restructured
• B. Capillary arcade forms anew
• C. Blood vessel formation
• D. Tissue contraction

Answer: (A)

During remodeling, the tissue that formed earlier as granulation tissue becomes a more organized and stronger scar. The capillary network that was created in the proliferative phase tends to regress, so the capillary arcade collapses. At the same time, the extracellular matrix is restructured: collagen is realigned and cross-linked, with a shift from the earlier, weaker type III toward stronger, more mature type I collagen. This combination increases the tissue’s tensile strength and stabilizes the scar. Forming a new capillary network and ongoing blood vessel formation are features of the proliferative phase, not remodeling. Wound contraction is more about pulling the edges together during healing and isn’t the central event of the remodeling phase.
