- The respiratory system is composed of the nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchi, and lungs
- The respiratory tract can be divided into the upper respiratory tract and the lower respiratory tract
- Upper respiratory tract: nose, nasal cavity, paranasal sinuses, pharynx, and larynx

Functional Divisions
- Conductive portion: nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchi, and progressively smaller airways within the lungs
- Respiratory portion: respiratory bronchioles, alveolar ducts, and alveolar sacs
Functions
- Primary function of the respiratory system: respiration (oxygen supply and carbon dioxide removal)
- Other functions: gas conditioning, sound production, olfaction, and defense
- Pulse oximetry: measures oxygen levels in the blood by detecting changes in hemoglobin molecules
Epithelium of the Respiratory Tract
- Respiratory epithelium: pseudostratified ciliated columnar epithelium with goblet cells, supporting cells, and basal cells
- Olfactory epithelium: located in the superior part of the nasal cavity, provides support and nourishment to olfactory receptor cells and basal cells
Nose, Nasal Cavity, and Paranasal Sinuses
- Nose: main conducting airway for inhaled air, divided into external nose and internal nasal cavity
- Nasal cavity: lined by respiratory epithelium, warms, humidifies, and filters air
- Paranasal sinuses: air-filled cavities within bones of the skull, produce mucus and help to warm and humidify air
Voice and Speech Production
- Voice is generated by airflow from the lungs, passing through the larynx and vocal folds
- Coordinated movements of the tongue and lips shape the sounds to form speech

Structural Divisions
- The respiratory system consists of the nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchi, and lungs.
- The respiratory tract can be divided into the upper respiratory tract and the lower respiratory tract.
- The upper respiratory tract includes the nose, nasal cavity, paranasal sinuses, pharynx, and larynx.
- The lower respiratory tract includes the trachea, bronchi, and progressively smaller airways within the lungs.
Functional Divisions
- The respiratory system can be divided functionally into a conductive portion and a respiratory portion.
- The conductive portion includes the nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchi, and progressively smaller airways within the lungs.
- The respiratory portion includes the respiratory bronchioles, alveolar ducts, and alveolar sacs, where gas exchange occurs between the air in the lungs and the blood.
Functions
- The primary function of the respiratory system is respiration, a multi-step process by which oxygen is supplied to the body and carbon dioxide is removed from the body.
- The respiratory system also has several other functions, including gas conditioning, sound production, olfaction, and defence.
Epithelium of the Respiratory Tract
- The respiratory tract is lined by two types of epithelium: respiratory epithelium and olfactory epithelium.
- Respiratory epithelium is a pseudostratified ciliated columnar epithelium that lines most of the conductive portion of the respiratory tract.
- Olfactory epithelium lines the superior part of the nasal cavity and is responsible for olfaction.
