Immune System Functions Defense against dangerous organisms Response to foreign invaders Three types 1st Anatomic 2nd Inflammatory 3rd Immune Immune System Foreign Invaders Pathogens Viruses, bacteria, fungus, parasites Expose/Infected Dose/Virulence/Host

Resistance Antigens Toxins Antibodies Viruses Hi-jack organelles & Spread to other cells Interferon (control) Cell before infecti on

and after. Immune System- Anatomic saliva antibacterial enzymes skin prevents entry stomach acid low pH kills harmful microbes tears

antibacterial enzymes Mucus & Cilia linings traps dirt and microbes Immune System- Inflammatory Increase of blood circulation Cells congregate Redness, swelling, heat, pain Acute (short)/Chronic(long) inflammation Innumerable Insults Tissue damage Healing/repair

Disorders Immune System - Immune Primary (non-specific) Response First time invaders Secondary (specific)Response Second time invaders/Immunological memory (antibodies) Immunity-Ability to fight off infection

Antibodies Active Immunity Ex. Exposure/Vaccination Passive Immunity Ex. Breast Feeding Immune System- Immune Phagocytes Consume and destroy (macrophages) 1. 2. 3. 4. 5.
