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.
