The innate immune system serves as the body's primary defense against pathogens, utilizing various components to protect health. Physical barriers like skin and mucous membranes act as a frontline defense, while phagocytes, such as macrophages and neutrophils, engulf and eliminate foreign invaders. Chemical agents in tears, saliva, and stomach acid neutralize threats, and inflammation signals the body's response to breaches, isolating and addressing issues. This system operates quickly and broadly, ensuring immediate protection while the adaptive immune system prepares a more specific response.
