The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.
The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.
The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.
Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.
Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).
