In which phase of tissue repair is the tissue structure restored?

The correct answer is that tissue structure is restored during the regeneration phase of tissue repair. This phase follows the inflammation stage, in which the body's initial response to injury occurs, characterized by redness, heat, swelling, and pain as blood flow increases to the area. During the regeneration phase, cells that were damaged or lost begin to proliferate and new tissue forms, leading to the replacement of lost or damaged structures with cells of the same type. This is crucial for restoring normal function to the impacted area.

Moving forward, the remodeling phase takes place after regeneration, during which tissue is reorganized and strengthened, and certain cells may be removed or replaced to enhance functionality. This stage refines and improves the quality of the newly formed tissue but does not involve the initial restoration of tissue structure. The inflammation phase is focused on damage control and preparing the area for healing, while degeneration usually refers to the decline or deterioration of tissue, which does not contribute to restoration.
