Sputum and mucociliary clearance mechanisms
  1. Lynne Reid

    Abstract

    Bronchial secretion forms a periciliary liquid layer and may also give rise to thicker secretion that moves on the tips of the cilia. This latter material as collected at bronchoscopy or coughed up as sputum is a viscoelastic substance behaving in a characteristic way over a wide range of shear rates. The anatomical basis of secretion is described and its control as established by organ culture.
