Study Notes

Respiratory System: Structure and Disorders

Pharynx (throat) is 12.5 cm long and divided into nasopharynx, oropharynx, and laryngopharynx.
The pharynx serves as a passageway for food and liquids, air distribution, and provides immune protection through tonsils.
The larynx, or voice box, is located below the pharynx and is responsible for air distribution and voice production.
Laryngeal cancer is more prevalent in men over 50 and may require alternative speech methods if the larynx is removed.
Upper respiratory infections include rhinitis, pharyngitis, laryngitis, epiglottitis, and croup.
Anatomical disorders such as deviated septum and epistaxis (bloody nose) can affect the respiratory system.
The trachea, about 11 cm long, functions as a passageway for air and is supported by C-shaped rings of cartilage.
Tracheal obstruction can cause death within minutes and is addressed through life-saving techniques such as the abdominal thrust maneuver and tracheostomy.
The bronchi, bronchioles, and alveoli are responsible for air distribution and gas exchange between air and blood.
Respiratory distress may result from inadequate surfactant production, leading to conditions like infant respiratory distress syndrome (IRDS) and adult respiratory distress syndrome (ARDS).
Lungs are large enough to fill the chest cavity, with an apex under the collarbone and a base resting on the diaphragm.
The pleura, a moist membrane, lines the chest cavity and covers the outer surface of the lungs, reducing friction during breathing.
