laryngopharynxes การใช้

• The vascular supply to the laryngopharynx includes the superior thyroid artery, the lingual artery and the ascending pharyngeal artery.
• At the mean pH of the laryngopharynx ( pH = 6.8 ) pepsin would be inactive but could be reactivated upon subsequent acid reflux events resulting in damage to local tissues.
• Due to the viscous properties of this upper mucous layer, the tips of the cilia catch in the layer, which may contain particulate matter, and drag it cranially toward the laryngopharynx.
• An air choke or tracheal choke specifically refers to a " true " choke that compresses the upper airway ( trachea, larynx or laryngopharynx ), hence interfering with breathing, and leading to asphyxia.
• The cilia of the respiratory epithelium beat in concert cranially, effectively moving secreted mucus containing trapped foreign particles toward the laryngopharynx, for either expectoration or swallowing to the stomach where the acidic pH helps to neutralize foreign material and micro-organisms.
