Functions of antibodies simplified

Antibodies swim around & bind to antigens. This prevents antigens from binding & damaging other cells.

Antibody binds to antigen.
Antibodies coat the antigen (opsonization) & alert the phagocytes to destroy (eat) the antigen.
Opsonization - Pathogen is marked for ingestion and destruction by a phagocyte. 
Antibodies activate the complement pathway to remove or destroy the pathogen.
Antibody activates complement cascade.

Mediates ADCC (Antibody-Dependent Cell-Mediated Cytotoxicity)

Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC)
What is ADCC?
An effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies. This is useful in killing cells that are infected by viruses & tumor cells who express different (non-self) molecules on their surface.

That's all!

Hey! Why did the antibody come dressed up as a skeleton for the halloween party?
Because it's an antibody! Get it? Anti-BODY?! HAHAHA!
