Functions of Complement system
The complement system is a critical component of the innate immune system that plays a vital role in recognizing and eliminating invading pathogens. Composed of more than 30 plasma proteins, the complement system is activated through several different pathways and exerts its effector functions through various mechanisms. These functions include opsonization, recruitment of inflammatory cells,…

Functions of Antibodies
This text provides an overview of the critical functions of antibodies, also known as immunoglobulins, in the immune response. Antibodies are a class of proteins that play a vital role in protecting the body from infection and disease. They are produced by B-lymphocytes and can bind specifically to a wide variety of antigens. Antibodies are…

Antigen-Antibody Reaction
The text above provides an overview of antigen-antibody reactions, which play a crucial role in the immune response. It explains the specific binding of an antigen to an antibody through non-covalent bonds and the diversity of antibodies generated by the immune system. The mechanisms of action resulting from antigen-antibody reactions are also discussed, including neutralization,…

Humoral Immune Response
The humoral immune response, also known as antibody-mediated immunity, is one of the two branches of the adaptive immune response. It involves the production of antibodies, also known as immunoglobulins (Ig), by B cells in response to an antigen. The purpose of the humoral immune response is to neutralize and remove antigens from the body.…
