Pulmonary Divisions
Amount of air that gets exhanged in single respiratory cycle
Tidal Volume
What muscles are being used in quiet breathing?
None
Pleura lines the ribcage (thorax)
Parietal Pleura
Active systems during /z/
Respiratory, Laryngeal, Articulatory, Velopharyngeal
VC(Vital Capacity)-ERV(Expiratory Reserve Volume)
Inspiratory Capacity( IC)
Circumferential measurement
RIP vest( Respitrace)
These muscles contract to inhale during quiet breathing
External Intercostal Muscles and Diaphragm
Active systems during /m/
Respiratory, Laryngeal, Articulatory
Key Factors that affect VC
Gender, Age, Height
Indirect measure for estimating subglottal pressure?
Intraoral pressure during /p/
Engulf carbon and toxins in lungs of a smoker
Macrophages
System responsible for voicing of sounds
Laryngeal
Breathing for speech occurs here
Inspiratory Reserve Volume (IRV)
I want to speak below REL , what do I need to counteract the passive forces?
Active Expiratory Muscles
The function of this structure is to conduct air/produce secretions and filter foreign particles
Bronchioles
muscle that separates trachea and esophagus
Trachealis
Limiting Factor of VC
Size of Ribcage
Used to maintain constant subglottal pressure and to control descent of the rib cage
Checking Action (during speech)
This structure is straighter than the other and tends to cause aspiration
Right bronchial tube
Calibrates Pneumotachograph
Rotometer
