Effect of Cilia Beat Frequency on Muco-ciliary Clearance

Background: The airway surface liquid (ASL), which is a ï‌‚uid layer coating the interior epithelial surface of the bronchi and bronchiolesis, plays an important defensive role against foreign particles and chemicals entering lungs.Objective: Numerical investigation has been employed to solve two-layer model consisting of mucus layer as a viscoelastic fluid and periciliary liquid layer as a New...

Motile cilia-specific protein macrocomplexes and cilia beating

In Eukaryotes, except fungi and higher plants, the coordinated beating of the motile cilia propels unicellular organisms and regulate the flow of the extracellular fluids in multicellular life forms. In humans proper beating of these tiny nanomachines ensures removal of the mucus and bacteria out of the airways, circulation of cerebrospinal fluid in brain ventricles, transport of the oocytes in...

The beat pattern and beat frequency of cilia and flagella

in many kinds of eukaryote are controlled by changes in intracellular Ca2+ concentration. Ciliary movement in Paramecium comprises two kinds of ciliary strokes, the effective stroke and the recovery stroke, and shows metachronal coordination (Machemer, 1972). When Paramecia meet an obstacle, their cilia reverse the direction of their beat, allowing the organism to swim backwards (Jennings, 1906...
