The immune system serves the crucial function of protecting the body against pathogens, including bacteria, viruses, fungi, and parasites. It achieves this through a complex network of cells, tissues, and organs that work in unison to identify and eliminate these harmful invaders. Key components of the immune system include white blood cells, antibodies, and various signaling molecules that coordinate the immune response. The system has the ability to distinguish between the body's own cells and foreign invaders, enabling it to mount an appropriate defense against infections.

This protective capability is vital for maintaining health, as it prevents infectious diseases and can also play a role in identifying and destroying cancerous cells. In summary, the primary role of the immune system is to safeguard the body from pathogens, making it essential for overall health and wellness.
