Study Notes
Pulmonary Volumes
- Tidal Volume • Approximately 500 ml of air is inspired or expired during a normal inspiration or expiration
- Inspiratory Reserve Volume • The amount of air that can be forcefully inspired after the normal tidal volume has been inspired
- Expiratory Reserve Volume • The amount of air that can be forcefully expired after the normal tidal volume has been expired
Respiratory System Divisions
- The respiratory system is divided into two main parts: the upper tract and the lower tract
- The upper tract consists of the nose, pharynx, and associated structures
- The lower tract consists of the larynx, trachea, bronchi, and lungs
- The respiratory tracts are lined with ciliated columnar epithelium
- The alveoli, responsible for gas exchange, are lined with single squamous nonciliated epithelium
- The different parts of the respiratory system include the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs
Pulmonary Volumes
- Tidal volume: approximately 500 ml of air inspired or expired during a normal inspiration or expiration
- Inspiratory reserve volume: additional air inspired forcefully after normal tidal volume inspiration
- Expiratory reserve volume: additional air expired forcefully after normal tidal volume expiration
Functions of the Nose
- Warms the air
- Cleans and filters the air
- Humidifies the air
- Enables the sense of smell
- Resonates speech
Respiratory System Divisions
-
Upper Respiratory Tract
- Consists of nose, pharynx, and associated structures
-
Lower Respiratory Tract
- Includes larynx, trachea, bronchi, and lungs
- Respiratory tracts lined with ciliated columnar epithelium
- Alveoli lined with single squamous non-ciliated epithelium
Functions of Pharynx (Throat)
- The pharynx acts as a passage for both air and food, facilitating their movement through the respiratory and digestive systems.
- The pharynx plays a crucial role in warming and humidifying inhaled air, preparing it for the lungs.
- The pharynx is involved in the sense of taste, as it houses taste buds that detect flavors in food and drinks.
- The pharynx contains lymphatic tissue in the form of pharyngeal tonsils, which produce antibodies to combat microorganisms and protect the body from infections.
- The pharynx plays a significant role in speech production, as it helps to modulate sound and articulate words.
