IMMUNOLOGY

Detailed explanation-1: -Inflammation serves as a defense mechanism against infection and injury, and localizing and eliminating injurious factors and removing damaged tissue components allows the healing process to begin. During the healing process, damaged cells capable of proliferation regenerate.

Detailed explanation-2: -The inflammatory response is an integral part of the innate immune mechanism that is triggered in response to a real or perceived threat to tissue homeostasis, with a primary aim of neutralizing infectious agents and initiating repair to damaged tissue.

Detailed explanation-3: -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.
