Questions and CORRECT Answers
Immunity - CORRECT ANSWER - process by which a host organism protects itself from
external and internal agents
Self v Nonself
acquired (specific) immunity - CORRECT ANSWER - formation of specific antibodies
and response, provides "memory" for previous encounters
Cellular Immunity - CORRECT ANSWER - *CELLS ANTIGENS*
Cells:
Macs, T-Cells, Dendritic Cells
Cytokines (Lymphokines and monokines)
Chemokines
Cytokines (as part of cellular immunity) - CORRECT ANSWER - *FLUID
ANTIBODIES* soluble peptide messenger
Lymphokines - lymphocytes
Monokines - by monocytes and macrophages
,Humoral Immunity - CORRECT ANSWER - fluid components of immune system
