The immune system is the body’s defense mechanism against infections and diseases, composed of a complex network of cells, tissues, and organs that work together to protect the body. Key components of the immune system include white blood cells (leukocytes), the spleen, thymus, bone marrow, and lymphatic system. The immune system operates through two primary responses: innate immunity, which provides immediate but non-specific defense against pathogens, and adaptive immunity, which involves a more specialized response tailored to specific invaders and includes the development of immunological memory. This memory allows the immune system to respond more rapidly and effectively upon subsequent exposures to the same pathogen. The immune system is also responsible for identifying and destroying abnormal cells, such as cancer cells, thus playing a vital role in preventing malignancies. Maintaining a healthy immune system is crucial for overall health and can be supported through proper nutrition, regular exercise, adequate sleep, and stress management.
