'''[[:zh:咳嗽|咳嗽]]'''是一種呼吸道常見的突發性症狀，咳嗽由氣管、支氣管黏膜或胸膜受炎症、異物、物理或化學性刺激引起，咳嗽時先是聲門關閉，呼吸肌收縮，肺內壓升高，然後聲門張開，肺內空氣噴射而出。通常伴隨著聲音。咳嗽具有清除呼吸道異物和分泌物的保護性作用。
A '''[[wikipedia:Cough|cough]]''' is a sudden and often repetitively occurring, protective reflex, which helps to clear the large breathing passages from fluids, irritants, foreign particles and microbes. The cough reflex consists of three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Coughing is either voluntary or involuntary.
