Explanation:
Lymphocyte :- They recognise proteins on the surface of pathogens called antigens . They are also use to detect that these are foreign, ie not naturally occurring within the body, and produce antibodies .
Antibodies :- They are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization) they also form complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
Antigens :- They are used to find and neutralize any potentially harmful foreign substances in the bloodstream. The specific binding between antigen and antibody is similar to that of the lock-and-key binding model.
