Verified step by step guidance

Understand the role of the immune system: The immune system is responsible for defending the body against pathogens, which are harmful organisms like bacteria, viruses, and fungi.

Differentiate between innate and adaptive immunity: Innate immunity provides immediate, non-specific defense against pathogens, while adaptive immunity is specific and has memory.

Explore the concept of immunological memory: The adaptive immune system can remember pathogens it has encountered before, allowing for a faster and more efficient response upon re-exposure.

Identify the components of the adaptive immune system: Key players include lymphocytes such as B cells and T cells, which are responsible for recognizing specific antigens and mounting a targeted response.

Recognize the primary function of the adaptive immune system: Its main role is to remember and specifically target pathogens that have been encountered previously, providing long-term protection.
