What is an example of a nonspecific response to a pathogen?

An example of a nonspecific response to a pathogen is the inflammatory response. When tissues are injured or infected, they release chemicals that lead to blood vessel dilation and increased permeability, allowing immune cells to migrate to the affected area. This response helps contain and eliminate pathogens, regardless of their specific identity, and aims to initiate healing. Other nonspecific responses include fever and the action of phagocytic cells like macrophages that engulf and destroy invading microorganisms.
