What is inate imunity?

Innate immunity is the body's first line of defense against pathogens, providing a rapid and non-specific response to infections. It includes physical barriers like skin and mucous membranes, as well as immune cells such as macrophages, neutrophils, and natural killer cells that can quickly recognize and attack foreign invaders. Unlike adaptive immunity, which develops over time and targets specific pathogens, innate immunity is present from birth and responds the same way to all infections. This system also involves various biochemical responses, including the release of cytokines and the activation of the complement system.
