Why we are here l.jpg
Why we are here

Infectious disease is something that everyone comes in contact with.

We need to know how to protect ourselves and those around us!

    • Internal-inflammation, interferon, natural killer cells,


Immune response18 l.jpg
Immune Response

  • Specific Resistance

    • Lymphocytes

      • Memory Cells

      • Effector Cells

      • B-Cells

      • Antibodies


Immune response19 l.jpg
Immune Response

  • Specific Resistance

    • Cell Immunity

      • T-Cells

      • Helper T-Cell Activation

      • Cytotoxic T-Cell Activation


Taking care of your immune system l.jpg
Taking Care of Your Immune System

  • Good Nutrition

    • Wash food

    • Refrigerate foods that spoil

    • Take Vitamins
