Detailed explanation-1: -Repeated injuries, chronic inflammation. Repeated injuries, chronic inflammation and repair are susceptible to fibrosis where an accidental excessive accumulation of extracellular matrix components, such as the collagen is produced by fibroblasts, leading to the formation of a permanent fibrotic scar.
Detailed explanation-2: -Chronic inflammation: Your body continues sending inflammatory cells even when there is no outside danger. For example, in rheumatoid arthritis inflammatory cells and substances attack joint tissues leading to an inflammation that comes and goes and can cause severe damage to joints with pain and deformities.
Detailed explanation-3: -Margination – cells line up against the endothelium. Rolling – close contact with and roll along the endothelium. Adhesion – connecting to the endothelial wall. Emigration – cells move through the vessel wall to the affected area.
