Immunology
  1. Immunology is the study of immune system that includes various cells, tissues and organs, working collectively and defend against harmful pathogens, cells and substances.
    1. Lines of Defences:

      Anmerkungen:

      • 1. First line  - External physical barriers  e.g skin2. Second line Internal physiological barrierse.g inflammation3. Third line- Adaptive immune response
      1. Components of Immune System
        1. Cardiovascular system

          Anmerkungen:

          • Heart and blood vessel
