Detailed explanation-1: -Inflammation. Injury or infection frequently leads to an inflammatory response characterized by redness, swelling, heat, and pain(Figure 1). Inflammation is part of the non-specific or constitutive defense system of the host.

Detailed explanation-2: -INNATE IMMUNITY. Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.

Detailed explanation-3: -Inflammation is a nonspecific response to any trauma occurring to tissues. It is accompanied by signs and symptoms that include heat, swelling, redness, and pain.

Detailed explanation-4: -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].
