Tissue repair is the process by which the body heals damaged tissues after injury or disease. This involves several stages, including inflammation, tissue formation, and remodeling. During inflammation, the body responds to injury by sending immune cells to the affected area to prevent infection and clear debris. Following inflammation, the body begins to form new tissue through a process called regeneration or fibrosis. In regeneration, cells replace damaged ones, while fibrosis involves the formation of scar tissue. Ultimately, tissue repair restores the integrity and function of the affected area, allowing the body to recover from injury.
