Fluid
, The average trachea is how long?
10-12 cm long
What area of the airways no longer have car#lage to hold them open?

Explain in rela#on to inhala#on, and exhala#on what the smooth muscle is doing.
On inhala#on the smooth muscle relaxes allowing the air to enter the alveoli, and on exhala#on
the smooth muscle contracts.
Name the areas of gas exchange
Terminal Bronchioles,Respiratory bronchioles these lead to alveolar ducts, then sacs, then to
the alveoli themselves
What are the three #ssue layers in the wall of the airways
Mucosa
Submucosa
Adven##a
What is the main cell type in the airways are?
Pseudostra#fied, ciliated columnar epithelum
Which type of cells are responsible for secre#ng Mucous?
Goblet Cells
The Cilia is responsible for what in the airway?
Clearing and defending the conduc#ng airways
What does the submucosal layer contain?
Bronchial glands which are the major source of respiratory tract secre#ons.
(An increase in bronchial glands = increase in secre#on produc#on in the airways)
Mast Cells
When the mast cells are s#mulated they excrete mediators such as?
