Final answer:
Etiologic factors of inflammatory lesions include tissue injury, chemical triggers, and inflammatory mediators. Tissue injury releases inflammatory mediators that cause vasodilation and increased capillary permeability, leading to swelling. Chemical triggers and inflammatory mediators stimulate the immune response.
Step-by-step explanation:
Etiologic factors of inflammatory lesions include tissue injury, chemical triggers like cytokines and histamines, and inflammatory mediators such as prostaglandins and leukotrienes. Tissue injury releases mast cell granules and inflammatory mediators, causing vasodilation, increased blood flow, increased capillary permeability, and swelling. Chemical triggers and inflammatory mediators stimulate the immune response, attracting leukocytes and promoting chemotaxis.
