Detailed explanation-1: -Inflammation is the immune system’s response to harmful stimuli, such as pathogens, damaged cells, toxic compounds, or irradiation [1], and acts by removing injurious stimuli and initiating the healing process [2]. Inflammation is therefore a defense mechanism that is vital to health [3].

Detailed explanation-2: -The goals of the inflammatory response are to: Prevent initial establishment of infection or remove damaged tissue. Prevent the spread of infection or repair damaged tissue. Recruit effector cells if the immune cells of the innate immune system cannot control infection or repair damaged tissue.

Detailed explanation-3: -The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury. Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that the body can begin to heal.

Detailed explanation-4: -It is now recognized that inflammation induced by microbial infection and tissue damage is an essential mechanism of innate immune response. Proper inflammatory responses provide broad spectrum protection against infections and orchestrate long-term adaptive immunity toward specific pathogens.
