People with cystic fibrosis are more susceptible to lung infections than those who don’t have the disease, but the reason why may be difficult for children to understand. In this video from CanadianCFMom, a young scientist named Elina, invites us into her lab to demonstrate how the lungs of cystic fibrosis patients work.
Using marbles and jars of cream, Elina shows us the difference between a healthy person’s lungs work to get rid of harmful bacteria versus the lungs of someone with cystic fibrosis. Her simple demonstration shows how bacteria becomes trapped in the lungs of cystic fibrosis patients as the mucus is too thick for bacteria to move through the lungs and be expelled.
