  2. Mucociliary clearance - Wikipedia

    en.wikipedia.org/wiki/Mucociliary_clearance

    Mucociliary clearance has a major role in pulmonary hygiene. MCC effectiveness relies on the correct properties of the airway surface liquid produced, both of the periciliary sol layer and the overlying mucus gel layer, and of the number and quality of the cilia present in the lining of the airways. [3] An important factor is the rate of mucin ...

  3. Respiratory epithelium - Wikipedia

    en.wikipedia.org/wiki/Respiratory_epithelium

    The respiratory epithelium functions to moisten and protect the airways. It acts as a physical barrier to pathogens, as well as their removal in the mechanism of mucociliary clearance. The ciliated cells are the primary components in the mucociliary clearance mechanism.

  4. Respiratory tract - Wikipedia

    These beat rhythmically out from the lungs, moving secreted mucus foreign particles toward the laryngopharynx upwards and outwards, in a process called mucociliary clearance, preventing mucus accumulation in the lungs. Macrophages in the alveoli are part of the immune system which engulf and digest any inhaled harmful agents.

    Mucociliary escalator, [4] surfactant, [3] defensins [3] Nasopharynx: Mucus, saliva, lysozyme [3] Eyes: Tears [3] Blood–brain barrier: endothelial cells (via passive diffusion/ osmosis & active selection). P-glycoprotein (mechanism by which active transportation is mediated)

  6. Mucoactive agent - Wikipedia

    en.wikipedia.org/wiki/Mucoactive_agent

    Mucokinetics: increase mucociliary transport (clearance) and transportability of mucus by cough [2] Mucoregulators: suppress underlying mechanisms of mucus hypersecretion [2] Alternatively, attacking the affinity between secretions and the biological surfaces is another avenue, which is used by abhesives and surfactants.

    The relationship escalator, coined by Amy Gahran, describes the traditional order of steps a relationship is expected to take, from monogamy to marriage.

  9. Aspiration pneumonia - Wikipedia

    en.wikipedia.org/wiki/Aspiration_pneumonia

    Atypical presentation is common in the elderly. Older patients may have impaired T cell function and hence, they may be unable to mount a febrile response. The mucociliary clearance of older people is also impaired, resulting in diminished sputum production and cough. Therefore, they can present non-specifically with different geriatric ...
