Respiratory System Concept Map
Major Functions of Respiratory System
Gas exchanges between blood and external environment
Passageways to lungs purify,warm,and humidify the incoming air
Anatomy of the Respiratory Tract
Nasal Cavity
Nostril
Oral Cavity
Pharynx
Larynx
Trachea
Left/Right Bronchus
Left/Right Lung
Diaphragm
Organs of the Respiratory System
Upper Respiratory Tract
Lower Respiratory Tract
Nose

Bronchial Tree
Lungs
Difference between Right/Left Lungs and Right/Left Primary Bronchi
Right Lung
Left Lung
Right Primary Bronchus
Left Primary Bronchus
2 lobes
3 lobes
Wider,shorter, and straighter than the left bronchus
Longer,thinner, and crooked than the right bronchus
Breathing Mechanism
Respiration
Entire process of exchanging gases between atmosphere and body cells
Pulmonary Ventilation
Movement of air in the Lungs
Inspiration
Flow of air into the lungs
Expiration
Flow of air out of the lungs
Definitions of Lung Capacity defenitions
Tidal Volume
Inspiratory reserve volume
Residual volume
Dead Space Volume
Amount of air left in aveoli after forrced expiration
Air moved in one respiration
Additional air taken in during maximal inhalation
Air remaining in conducting zone
Expiratory reserve volume
Additional air forced out during maximum expiration
Inspiration Capacity
tidal volume+inspiratory reserve volume
Functional Residual capacity
residual volume+expiratory reserve volume
Vital Capacity
inspiratory reserve volume+ tidal volume+expiratory reserve volume
Total lung capacity
Sum of all volumes
External and Internal Respiration
External Respiration
Internal Respiration
occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells
occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air.
Disorder of Respiratory System
COPD
Labored of difficulty breathing becomes progressively more painful
Emphesyma
Alveoli enlarge as adjacent chamber break through causing chronic inflammation which promotes lung fibrosis
Chronic Bronchitis
Mucosa becomes inflamed which also increases production and impairs ventilation
Lung Cancer
1/3 of all cancer deaths in the US and is associated with smoking
SIDS
Asthma
Chronic inflamed hypersensitive bronchiole passages
Unexplained infant death which may be cause by neural respiratory control center
