What does lower airway mean?
The second half of the human airways, continuing after the larynx, including the trachea, bronchi, and the respiratory structures within the lungs – the, bronchioles, and alveoli, is referred to as the lower respiratory tract [1, 2].
What is the function of the lower airway?
→ The upper airway functions to warm, filter and humidify air while providing a passage for air to enter the body. → The lower airway’s main function is gas exchange. → Alveoli – Gas exchange takes place here. → Bronchi – The right mainstem bronchus is shorter, wider and more straight than the left mainstem bronchus.

What is the lower respiratory tract?
Lower respiratory tract refers to the lowermost section of the respiratory tract, which is mainly involved in the gas exchange. It includes structures such as trachea, bronchi, bronchioles, and alveoli. Bronchi arise from the trachea by dividing the trachea into two as right primary bronchus and left primary bronchus. Primary bronchi further divide into secondary and tertiary bronchi. Bronchi form bronchioles. The three types of bronchioles are lobular bronchioles, terminal bronchioles, and respiratory bronchioles. Trachea, bronchi and bronchioles are made up of pseudostratified epithelium. The components of upper and lower respiratory tract are shown in figure 2.
