Q32: Congenital malformations of trachea and bronchus

Q32.4: Other congenital malformations of bronchus

The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways.

While developing in the womb, many different types of tissue develop in the body. The organs and body parts develop out of the various types of tissue. If tissue fails to develop properly, defects can occur. Defects can involve tissue being missing or changed, for example. Tissue may also form in an unusual place. Depending on the type of defect, there can be various indications.
