Q34: Other congenital malformations of respiratory system
Q34.9: Congenital malformation of respiratory system, unspecified
When we breathe, the air gets into the body via the respiratory tract. The respiratory tract can be divided into the upper and the lower respiratory tracts. The nose and throat form part of the upper respiratory tract. The lower respiratory tract begins at the larynx. This includes the trachea and the bronchia.
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.
