What is Pathology - What factors influence the appearance of inflammatory reactions?
-Etiology: The nature of the pathogen that produced the lesions determines the shape of the lesions. Abscesses are frequently caused by bacteria that generate pus, such as Staphylococcus aureus. Cavitary lung lesions are frequently formed as a result of caseous necrosis, a tuberculosis symptom.
-Location: The anatomical characteristics of the organ in question are one of the most important drivers of the type of inflammation that occurs. Certain types of inflammation, such as ulcers, arise solely on the mucosal surface or on the skin, not in substantial organs like the liver or kidneys. Only mucosal areas with mucus-secreting cells, such as the nasal or bronchial mucosa, are affected by catarrhal inflammation.
-The duration of the inflammation: Acute inflammation is more exudative, whereas persistent inflammation is more likely to cause fibrosis and scarring.
