Title: The Human Immune System: Our Body's Defense Mechanism
The Human Immune System: Our Body's Defense Mechanism Introduction: The human body is constantly under attack from harmful pathogens like bacteria, viruses, and fungi. Fortunately, we have a built-in defense system—the immune system—that protects us from these invaders. In this blog, we'll explore how the immune system works, its different components, and why it's crucial for maintaining our health. What is the Immune System? The immune system is a network of cells, tissues, and organs that work together to defend the body against harmful invaders, such as bacteria, viruses, parasites, and fungi. It can recognize and respond to foreign substances (antigens), protecting us from infections and diseases. Key Components of the Immune System: 1.
