RESPIRATORY SYSTEM

Question 1

Lower respiratory tract is lined by specialised respiratory epithelium Location

Answer 1

Trachea, Bronchi, Bronchioles

Question 2

Describe the Trachea

Answer 2

The trachea is lined with pseudostratified ciliated columnar epithelium, which extends down to the main bronchi

Question 3

Describe the Bronchi

Answer 3

The main bronchi (primary bronchi) also feature this epithelium. As the bronchi branch into smaller bronchi (secondary and tertiary), the structure of the epithelium begins to change.

Answer 4

In the smaller bronchioles, the epithelium transitions to a simple cuboidal epithelium, particularly in the terminal and respiratory bronchioles.
