Adaptive immunity is the branch of

Position 1: It is this immunological memory that enables the body to mount a faster and more powerful response if the same pathogen is encountered again.

Position 2: Upon recognising an antigen, B cells and T cells proliferate and differentiate into effector cells that neutralise or destroy the pathogen.

Position 3: Adaptive immunity is the branch of the immune system that generates highly specific responses to pathogens encountered by the body.

Position 4: Crucially, a subset of these activated lymphocytes persists as memory cells long after the infection has been cleared.

Position 5: Unlike innate immunity, which provides a rapid but generalised defence, adaptive immunity relies on lymphocytes that recognise particular molecular signatures called antigens.
