The film discusses the anatomical and functional significance of the nose, throat, and ears from a medical perspective. It explains how the nose functions as an air passage that warms and filters ...

Premature infants are at risk of bronchopulmonary dysplasia, or BPD, a type of lung injury associated with increased mortality.

Cilia work by “beating,” or moving in coordinated pulses to propel mucus out of the body ... used high-speed video microscopy to observe nasal samples from nine infants with BPD, analyzing ...

When an inflammatory response occurs, immune cells release inflammatory chemicals, which lead to swelling and increased mucous ... overuse of nasal sprays can also damage the cilia that filter ...

This cold environment slows down those protective cilia, making them sluggish and less effective at their pathogen-sweeping job. Even more concerning is what happens to the mucus in your nose.

“Dry air increases mucus production in the nose and reduces cilia function, disrupting the crucial airway clearance needed for breathing,” Hapner said. “It also causes dehydration of both tissue and ...

“Saline irrigation can enhance the function of nasal cilia, those microscopic hairs that are responsible for moving mucus and trapped particles out of the nasal passages,” says John ...

Air pollution Bacteria and viruses Dirt Dust Pollen Nasal mucus traps these substances in the hairs of your nose (cilia). The air that passes through your nose when you breathe dries up the snot ...

Excess mucus clogs nasal passages and reduces the function of hairlike cells in the nasal passages, known as cilia, whose rhythmic beating clears harmful cold viruses. Nasal irrigation with ...
