Q
What are the 5 functions of the Respiratory System
A
- Provides extensive gas exchange surface area
between air and circulating blood - Moves air to and from exchange surfaces of
lungs - Protects respiratory surfaces from outside
environment - Produces sounds
- Participates in olfactory sense

5
Q
The Respiratory Tract has two portions. Name them and locations
A
The Respiratory Tract
Consists of a conducting portion
* From nasal cavity to terminal bronchioles
Consists of a respiratory portion
* The respiratory bronchioles and alveoli
6
Q
respiratory portion
A
- The respiratory bronchioles and alveoli
7
Q
conducting portion
A
- From nasal cavity to terminal bronchioles
8
Q
Alveoli is what and what takes place there?
A
- Are air-filled pockets within the lungs
- Where all gas exchange takes place
9
Q
For gases to exchange efficiently in the the respiratory epithelium…
A
- Alveoli walls must be very thin (<1 µm)
- Surface area must be very great (about 35 times
the surface area of the body)
10
Q
The Respiratory Mucosa
* Consists of
A
- An epithelial layer
- An areolar layer called the lamina propria
11
Q
The Respiratory Mucosa lines
A
the conducting portion of respiratory system
