Questions and CORRECT Answers
Immune System (IS) - CORRECT ANSWER - Tissues, cells and biological mediators that
work together defending or protecting host organism from foreign substances and abnormal cells
Immunity - CORRECT ANSWER - Process by which a host organism protects itself from
attacks by external and internal agents
Acquired immunity - CORRECT ANSWER - Formation of specific antigen-antibody and
specific responses
Self - CORRECT ANSWER - Anything that is derived from the host
Nonself - CORRECT ANSWER - Anything physically outside the host

ANSWER - Cellular and humoral immunity
Cellular immunity - CORRECT ANSWER - Mediated by various IS cells

, Chemokines - CORRECT ANSWER - Attractant molecules that interact between cells and
complement proteins and are important in destroying pathogens
Phagocytes - CORRECT ANSWER - Complex molecular structures on surface of
invading cells or in secretions and fluids of the host body
