Eupnea
Normal breathing
Expiration
Exhaling
- Breathing
- Pulmonary ventilation
Functions of the nose
- warms and moistens/ humidifies air
- smell
In the Upper Respiratory Tract
- Nose
- Pharynx/Throat
- Larynx
Hyperventilation
Rapid and deep breathing
Spirometer
Measures amount of air exchanged in breathing
- Pneumothorax
~ air within intrapleural space
Functions of the Pharynx
- Passageway
~ food
~ liquids
~ air
- Trachea
- Bronchial tree
- Lungs
hypoventilation
Slow and shallow breathing
Respiration
Exchange of gases between a living organism and its environment
Functions of the Bronchial Tree
Trachea, Bronchi, Bronchioles
- air distribution
- passageway
- air move to & from alveoli
Functions of the Larynx
- Air distribution
~ passageway for air
~ to and from the lungs
- Voice production
- Epiglottis:
~ protects trachea & lungs
~ prevents aspiration
Dysfunction of the Trachea
- Obstruction
~ blockage of trachea = airway occlusion
~ complete blockage
-> death in minutes
~ tracheal obstruction
- > 4000 deaths annually US
Dyspnea
Labored or difficult breathing
Respiratory Arrest
- after a period of apnea
- failure to resume breathing
Functions of the Bronchial tree
Alveoli
-gas exchange
- exchange gases between air and blood
Function of the Pleura
- Reduces friction during breathing
~ between the lungs and chest wall
Apnea
No respiration
Cheyene-Stokes
Some functions of the respiratory system
- filters incoming air
- humidifies incoming air
- distribute air
- gas exchange
Function of the Trachea
Passageway for air to move to and from lungs
