• Internal-inflammation, interferon, natural killer
  cells,

18
Immune Response

• Specific Resistance
• Lymphocytes
• Memory Cells
• Effector Cells
• B-Cells
• Antibodies

19
Immune Response

• Specific Resistance
• Cell Immunity
• T-Cells
• Helper T-Cell Activation
• Cytotoxic T-Cell Activation

20
Taking Care of Your Immune System

• Good Nutrition
• Wash food
• Refrigerate foods that spoil
