    Several diseases are caused by inhaling asbestos fibres. Most of these
    diseases result from the build up of these tiny asbestos fibres in the lungs.
    One of these diseases is asbestosis. The asbestos fibres are very small and
    enter the bronchioles and alveoli. They cause the destruction of phagocytes
    and the surrounding lung tissue becomes scarred and fibrous. The fibrous
    tissue reduces the elasticity of the lungs and causes the alveolar walls to
    thicken. One of the main symptoms of asbestosis is shortness of breath
    caused by reduced gas exchange.
    People with asbestosis are at a greater risk of developing lung cancer. The time
    between exposure to asbestos and the occurrence of lung cancer is 20–30 years.
    Use information in the passage and your own knowledge to answer the
    following questions.
    6 (a) Destruction of phagocytes (lines 4–5) causes the lungs to be more susceptible to
    infections. Explain why

    You pretty much have to write out the notes specific to phagocytes for that question, going into detail about how the phagocytes perform phagocytosis to prevent infections if the question is more than two marks

    i know about phagocytes .but i dont understand question in question he says destruction of phagocytes leads to infection in lungs

    i think i am making it complicated but honestly i don't understand question

    any one can explain question

    An infection in the lungs will be the result of pathogens propagating inside the lungs and releasing toxins. Phagocytes kill the pathogens. So, less phagocytes leads to...?

    Pathogen = infection

    Phagocytes = no pathogen

    No phagocytes = ....?

    It's not really that confusing a question tbh. Assuming you're an AS student, you probably will just have to learn to think more methodically e.g. "what do phagocytes do?" and "what is an infection" before you answer questions, rather than rushing in like you could do at GCSE

    Yeah I'm As student
    Well
    Question is saying
    Destruction of phagocyte leads to infection

    Infection is caused by pathogens. Pathogens release chemical that attracts phagocyte. Phagocyte engulf pathogen and release enzyme that destroy pathogen. As phagocyte destroy pathogens then there would no infection PHAGOCYTE DOES NOT LEAD TO INFECTION INFACT IT DESTROYS INFECTION CAUSING PATHOGENS........

    Exactly, that's why no phagocytes = infection. I'm assuming you're confused, or maybe you're angry? It's hard to tell
