INTRODUCTION TO IMMUNOLOGY (PART 1)

3 COMPONENTS OF IMMUNE SYSTEM
1. Cardiovascular System
  1. Heart
  2. Blood vessels
  3. Basically moves blood throughout the body
2. Mononuclear Phagocyte System
  1. Network of reticular fibres
  2. Phagocytes (macrophages)
  3. Cells engulf and destroy the microorganism and harmful substances
3. Lymphatic System
  1. To transport lymph
  2. Have lymphatic vessels
  3. Lymph node
ORGANS OF LYMPHATIC SYSTEM
1. Primary lymphoid organ
  1. Bone marrow
  2. Thymus
2. Secondary lymphoid organ
  1. Adenoid
  2. Tonsils
  3. Lymph nodes
  4. Spleen
  5. MALT
3. Lymph circulatory system
  1. Lymphatic vessels
CELLS OF IMMUNE SYSTEM
1. Platelet
First Line Defense
1. Saliva - antibacterial enzymes
2. Skin - prevents entry
3. Stomach acid - low pH kills harmful microbes
4. Tears - antibacterial enzymes
5. mucus - traps dirt and microbes
SECOND LINE : PHYSIOLOGICAL BARRIER
1. Create hostile environment for the invaders
2. Fever, Inflammation, Phagocytosis, Antimicrobial proteins
