Understanding the Immune System
What Is the Immune System? Your immune system is a complex network of cells, tissues, and organs designed to protect your body from harmful invaders like bacteria, viruses, and toxins. Think of it as your body’s security system, always on alert to fight off threats. Key Components of the Immune System: White Blood Cells (Leukocytes) – Detect and destroy harmful organisms. Antibodies – Help recognize and neutralize foreign substances. Lymph Nodes – Act as filters for harmful pathogens. Spleen – Helps fight infections and removes damaged blood cells. Bone Marrow – Produces immune cells like white blood cells. Thymus – Trains and develops T-cells for immune response.
