- - - - Erythrocytes
        
        Carry O2 and some CO2
        
        red blood ceels
      - Leucocytes
        
        Destroy antigens
        
        Neutrophils
        
        B-type cells
        
        Produces antibodies
        
        Lymphocytes
        
        T-type cells
        
        Destroy viruses and cancer cells
        
        Monocytes
        
        Removes dead cells and bacteria
        
        white blood cells
      - Platelets
        
        Trigger blood clotting
- - - - high density lipoprotein -> reverses the fat deposit in artery wall
      - low density lipoprotein -> deposited fat into artery walls
    - - iron containing protein
      - haemoglobin + oxygen= oxyhaemoglobin
      - no nucleus to increase space for haemoglobin
      - special disc shape to exchange oxygen
  - - - b-type lymphocytes = antigens
        
        make them a target for monocytes
      - lymphocytes remember so they can detect easier
        
        vaccination
    - - cant live independently
      - hijack other cells
      - t-lymphocytes catch and destroy
  - - - pathogens can access
    - - convert soluble (fibrinogen) into an insoluble (fibrin) net like
