1. Immune system-body's natural defense system

1.1. Various cells, tissues, organs

1.2. Work collectively

1.3. Against harmful pathogens,cells and substances

2. Components

2.1. Cardiovascular

2.1.1. Heart, blood vesseld

2.2. Mononuclear phagocyte system

2.2.1. Reticular fibres network

2.2.2. Exp: macrohages

2.3. Lymphatic system

2.3.1. Lymphoid organs

2.3.1.1. Primary

2.3.1.1.1. Production sites

2.3.1.1.2. Maturation sites (w/o antigen)

2.3.1.1.3. Exp: bone marrow, thymus

2.3.1.2. Secondary

2.3.1.2.1. Maturation sites (with antigen)

2.3.1.2.2. Differentiate into mature antigen-specific effector cells

2.3.1.2.3. Exp: adenoid, tonsils, lymph nodes, spleen, MALT
