Mouth - when we are eating and breathing

Pathogens have antigens on their surface that are unique to them.
A lymphocyte with an antibody that fits the antigen perfectly is activated.
This lymphocyte repeatedly divides to produce clones of identical lymphocytes
Some of the lymphocytes secrete large amounts of antibodies to destroy the pathogen.
Other lymphocytes remain in the blood as memory lymphocytes, ready to respond if the same antigen ever turns up again.
