Question

What part of the body creates the excess mucus in Cystic fibrosis?

1) Nose
2) Lungs
3) Pancreas
4) Thyroid

Answer 1

Cystic Fibrosis is caused by mutations in the CFTR gene, leading to the production of thick and sticky mucus, particularly in the lungs (option 2) which create excess mucus, affecting breathing and increasing the risk of infections.

Step-by-step explanation:

The part of the body that creates excess mucus in Cystic Fibrosis is primarily the lungs. This condition is an autosomal recessive genetic disease caused by mutations in the CFTR gene which results in the production of thick, sticky mucus. This mucus clogs not only the lungs but also affects other organs, including the pancreas. In the lungs, the abnormal mucus obstructs airways, impairs cilia function, and makes it difficult to clear bacteria, leading to frequent respiratory infections. In the pancreas, the mucus obstructs the passageways, hindering the release of digestive enzymes and thus affecting nutrient absorption.
