Maria, a volunteer firefighter in New Jersey, rushed along with the rest of her fire company to lower Manhattan on that awful morning of September 11, 2001

As they crossed over the Hudson into the city, they heard that the towers had collapsed, so they helped search through the rubble and dust from the buildings to find survivors. Maria has now developed serious health problems based on her exposure to the rubble and dust, which included asbestos and many other small particles. Which organ system and which organelle do you think are most likely failing in this brave woman's body?


Because Maria was exposed to many airborne particles within the rubble as well as inhaled the dust, it is likely that her respiratory system has been damaged. Lysosomes inside the cells cleaning the respiratory passages cannot break down asbestos. These small particles destabilize the membranes of the lysosomes, causing the release of enzymes in the respiratory tract and scarring of Maria's lung tissue.
