Your Body's Defense The Science Behind Immunity and Antibacterial Systems
Introduction Our bodies are under constant siege from a microscopic army of invaders – bacteria, viruses, and fungi. Yet, we rarely fall ill. This is thanks to our incredible immune system, a complex network of cells, tissues, and organs that work tirelessly to protect us. Let’s delve into the fascinating world of our body's defenses. Understanding Immunity Antibacterial System What is Immunity? Immunity is the body's ability to resist infection and disease. It's a complex interplay of physical barriers, innate immune responses, and adaptive immunity. Innate Immunity: This is our first line of defense. It includes: Physical barriers like skin and mucous membranes Chemical barriers like stomach acid and enzymes Cellular defenses like phagocytes that engulf and destroy invaders Adaptive Immunity: This is our body's specific response to a particular pathogen. It involves: B cells producing antibodies to neutralize threats T cells directly attacking infected cells Mem
