Abstract
Cilia-generated fluid flow between two strips of frog palate epithelium has been measured and flow velocity profiles have been obtained from the data. The strips are mounted in a covered chamber so as to form a ciliated channel and fluid motion is marked by suspended 1.0 μm polystyrene latex spheres which act as tracers. Results from a control non-mucus system and a 40% – 50% v/v mucus system are compared with predictions of a theoretical model. This theory for flow in mucociliated channels incorporates flow due to a static pressure drop between the channel ends and a difference in the cilia tip speeds between the two strips.
