Respiratory System & Respiratory Disorders Flashcards
Oxygen enters and carbon dioxide leaves
Respiration
Altered by changing blood CO2 levels
Regulation of blood pH
Movement of air past vocal folds makes sounds and speech
Voice production
Smells occurs when airborne molecules drawn into nasal cavity
Olfaction
Against microorganisms by preventing entry and removing them
Protection
Upper Respiratory System
Nasal cavity, nostril, mouth, larynx, pharynx
The dividing line between the upper and lower respiratory systems
Larynx
Lower Respiratory System
Trachea, right main bronchus, left main bronchus, right lung, left lung, diaphragm
Involves moving air in and out of the lungs
Pulmonary ventilation
Volume of air inspired or expired during a normal inspiration or expiration
Tidal volume
Amount of air inspired forcefully after inspiration of normal tidal volume
Inspiratory reserve volume
Amount of air forcefully expired after expiration of normal tidal volume
Expiratory reserve volume
Volume of air remaining in respiratory passages and lungs after the most forceful expiration
Residual volume
Tidal volume plus inspiratory reserve volume
Inspiratory capacity
Expiratory reserve volume plus the residual volume
Functional residual capacity
