Passages that are lined with mucous membranes and tiny hairs (cilia) that help to filter the air ... The larynx also serves as a passageway to the windpipe (trachea). Epiglottis. This is located above ...

The trachea ends at a ridge of cartilage that separates and forms the junction into the bronchi (carina). Mucosal membranes are made up of epithelial cells, mucus-secreting goblet cells, and hair-like ...

The nose hair’s job is to filter the air you ... You have a similar setup in your windpipe – also called the trachea. There, the cilia move the mucus up the windpipe like an escalator.

The trachea is also lined with tiny hair-like structures called cilia. These help push mucus that contains debris or pathogens out of the trachea. A person then either swallows or spits out the mucus.

(CREDIT Gizem Gumuskaya, Tufts University) Researchers provided human cells, which typically serve mundane functions in the trachea, an opportunity to ... These cells possess cilia, hair-like ...

The cells of the inner trachea are covered in hair-like projections called cilia, which move together to help push out mucus. In their new study, the Levin lab grew similar organoids under ...

A team of scientists created them using human cells from the trachea. Part of the reason why they used those cells is because they are covered with cilia, or tiny, hair-like projections.
