In the remodeling phase, which change describes the capillary network?

• A. Capillary arcade collapses
• B. Capillary density increases dramatically
• C. Capillary network expands but not collapses
• D. Capillary network remains unchanged

Answer: (A)

During remodeling, the capillary network becomes less dense as the tissue matures and gains strength. Vessels regress and the capillary arcade can collapse because the demand for a high blood supply decreases as collagen realigns and tensile strength increases. This is why describing the capillary arcade collapsing fits remodeling best. The other patterns describe earlier phases: capillary density increasing dramatically happens with granulation tissue formation, a continually expanding capillary network without collapse would imply ongoing angiogenesis beyond remodeling, and remaining unchanged would ignore the vascular regression that accompanies maturation.
