Explanation: 

Detailed explanation-1: -The inflammatory response has four phases: inflammatory inducers (infection or tissue damage), inflammatory sensors (mast cells and macrophages), inflammatory mediators (cytokines, chemokines, etc.) and the tissues that are affected. Each phase has many options that are triggered based on the type pathogen introduced.

Detailed explanation-2: -They release various substances, known as inflammatory mediators. These include the hormones bradykinin and histamine. They cause the small blood vessels in the tissue to become wider (dilate), allowing more blood to reach the injured tissue.
