Immune responses defend against pathogens from "summary" of The Biology Book by DK
When pathogens invade the body, the immune system goes into action to protect against these harmful invaders. The immune response is a complex network of cells, tissues, and organs working together to identify, target, and destroy pathogens that could potentially cause harm. The first line of defense is the innate immune system, which provides immediate, nonspecific protection against a wide range of pathogens. This includes physical barriers like the skin and mucous membranes, as well as cells like macrophages and neutrophils that engulf and destroy pathogens.
