        B lymphocytes
        
        make antibodies (protective proteins) which target bacteria,viruses and other foreign materials
        
        Neutrophils
        
        small and fast and are the most common type of white blood cell
        
        the immediate response cell and live less than a day
        
        Monocytes
        
        largest cells and can locate bacteria from a distance and move towards it the ingest infectious agaents such as basteria
        
        Platelets

    - - main focus is to deliever oxygen to the tissues in our body and carbon dioxide to our lungs for us to exhale
        
        prodcued in bone marrow
        
        diameter 6-8μm
        
        Biconcave disk (dougnut shaped) ensures lare surface area to volume ration for efficient gas exchange
        
        they get their colour from haemaglogin
        
        no nulceus
  - - - piece of the atheroma breaks off causing blood clout to form and blocking off the cornary artery cutting off the supply of oxygen - rich blood to the heart which can permanetly damage the heart
    - - fatty materials called atheroma building up in the arteris walls slowing or stopping the supllment of oxygen rich blood
- - - - Symptoms:
        
        Stomach pain or cramps, bloating (uncomfortably full and swolen), diarrhoea (watery poo & urges to poo) and constipation (can't poo).
      - Treatment
        
        Diet and lifestyle changes, increase in physical activity, fluid intake (mostly water) should be increased,
      - Monitoring

        Walls in the intestine are lined with mucsles contract, contractions that are stronger and longer than normal cause gas, bloating and diarrhoea while weak contractions can lead to slow food passage and hard dry stools.
    - - symptoms
        
        unexpted weight loss, extreame fatigue, nerve damage (impact on movements, memories, ability to think clearly), itchy rash, if it were developed at a young age it could cause the child to not grow at the expted rate and may have delyaed puberty
      - treatments
        
        change in diet avoiding foods with gluten,
