Platelets do not circulate in inactivated, spiny forms. The spiny, sticky form of the platelet is initiated once the platelets become activated in response to blood vessel damage.

The term affinity refers to the strength of attraction between a single antigenic determinant and a corresponding antigen binding site. The term avidity refers to the total strength of the attraction between an antibody and a multivalent antigen. The reaction between an IgM molecule (which has 10 antigen binding sites), and a multivalent antigen is therefore much stronger than that of an IgG antibody (which has only 2 antigen binding sites).
Avidity is best described by which of the following statements:
