  1. 1What is the purpose of mucus?
    1. ATo trap dust and other microorganisms.
    2. BMaintain rhythm like gas exchange.
    3. CEnsure transport of ions.
  2. 2What is the properties of mucus in a person struggling with CF?
    1. AMucus is runnier
    2. BMucus contains segments of blood
    3. CMucus is stickier
  3. 3What is the purpose of cilia in the lungs?
    1. ADissable pathogens.
    2. Bkeep the lungs clean
    3. CRegulate blood flow
  4. 4How do cilia fulfill it's purpose?
    1. AUsing enzymes present in the epithelial cells.
    2. Bby beating and moving substances along the tube they line.
    3. Cinflating and deflating, propelling durt through open pores.
  5. 5What are they three types of epithelial cells?
    1. Asquamous
    2. Bcubodial
    3. Cspherical
    4. Dcolumnar
  6. 6Mucus lines the airways in the lungs. Mucus traps [blank_start]dust[blank_end] and [blank_start]microorganisms[blank_end]. Mucus is removed by the [blank_start]cilia[blank_end] in a wave like motion. A person with CF struggles with [blank_start]stickier[blank_end] mucus. This mucus is [blank_start]harder[blank_end] to remove by the cilia.
    1. Adust
    2. Bmicroorganisms
    3. Ccilia
    4. Dstickier
    5. Eharder
  7. 7The stickier the mucus, the more the mucus builds up. Thus [blank_start]increasing[blank_end] the distance at which [blank_start]respiratory[blank_end] substances diffuse through. In turn [blank_start]reducing[blank_end] the rate of diffusion and making gas exchange [blank_start]less[blank_end] efficient.
    1. Aincreasing
    2. Brespiratory
    3. Creducing
    4. Dless
  8. 8White blood cells fight infection however how do they cause a problem in a person struggling with CF (in terms of mucus)?
    1. AWhen white blood cells die they break down and release Dna which makes the mucus even sticker.
    2. Bwhen white blood cells come into contact with mucus then release antibodies which break down the epithelial cells.
    3. CWhite blood cells And sodium present in the mucus react triggering mitosis.
