Question

Harry suffers from cystic fibrosis and has severe breathing difficulties.His problems result from
A)inability of the respiratory defense mechanism to transport mucus.
B)uncontrollable laryngospasms.
C)production of thick secretions that are difficult to transport.
D)both the inability of the respiratory defense mechanism to transport mucus and the production of thick secretions that are difficult to transport.
E)All of the answers are correct.

Accepted Answer

Cystic fibrosis is a genetic disorder that affects the production of mucus, sweat, and digestive juices. In the case of respiratory system, the mucus produced is thick and sticky, making it difficult for the cilia to move the mucus out of the airway passages. This leads to breathing difficulties and recurrent infections. Therefore, option D, which states that the problems are caused by both the inability to transport mucus and the production of thick secretions, is the best choice.
