Patient was educated on the various parts of conduction zone of the respiratory tract along with their functions as follows:
- Larynx
- Apart from helping in conduction of moist and warm air from the nasopharynx to trachea, larynx also contributes to the important function of generation of sound while speaking.
- So, larynx is also called the voice box.
- Trachea
- Trachea receives the moist and warm air from larynx and helps conducting it to the bronchi, the next part along the conduction zone of respiratory tract.
- Bronchi
- Trachea divides into 2 primary bronchi, right bronchus and left bronchus, entering respective lungs, on either side of the chest.
- These primary bronchi after entering the lungs divide into smaller secondary bronchi, which further divide into further smaller tertiary bronchi and bronchioles.
- Air from the trachea passes through all these structures and reaches the terminal bronchioles.
All these structures apart from helping conducting air in during inspiration also help in conducting air out during the process of expiration.
