Cricoid Cartilage
33
Controls the passage of Air through Mouth and into the Larynx
Pharynx
34
The main Trunk of system of tubes which air passes to and from the lungs
Trachea
35
Tubes that carry air into and out of the Lungs
Bronchi
36
Bronchi branches out and decreases into
Bronchioles
37
Bronchioles branches out and decreases into
Terminal Bronchioles
38
Terminal Bronchioles and decreases into
Respiratory Bronchioles
39
These are branches of the Bronchi that is embedded in the Lungs
Bronchioles
40
Two (2) Types of cells found in the Alveoli
Type I - Pneumocytes Type II - Surfactant
41
Makes the structure of the Alveoli and forms air-blood barrier where Gas Exchange occurs
Type I - Pneumocytes
42
Decreases surface Tension of the Alveoli
Surfactant

51
Lines the Chest Cavity
Parietal Pleura (Outer Layer)
52
These lines the Pleural Cavity
Visceral Pleura & Parietal Pleura
53
A liquid found between the layers of the pleura and serves to reduce friction
Pleural Fluid
54
Atmospheric Pressure is Greater during Inspiration / Inhilation
because lungs expands and air goes in Patm = 760 mmHg
55
Is Inspiration an Active Process or Passive Process
Active Process - because it aids the innervation of motor nerves
56
Is Expiration an Active Process or Passive Process
Passive Process
57
Atmospheric Pressure is Weaker during Expiration
Lung pressure: 759 mmHg
