it filter and warms the air
If they have pseudopods, cillia or flagella they can move.
Cillia
Cillia is an incorrect spelling of cilia, which are hair-like structures found on the surface of cells. Cilia are involved in movement and in helping to move fluids over the cell surface.
cillliated epillithial cells or cillia for short, they clean dust and mucus from our lungs
The seperate structure within a cell is called the cillia and flagella.
Cillia sre slim, microscopic hair-like organelles that extend fro the top of almost all mammalian cells.
They do not stop it but the mucus and motion of the cillia remove said microbes and dust should they get into the lungs.
cillia
Cillia are small hairs that have the function of "sweeping" tubes in our bodies. The cillia in our lungs sweep dust and other impurities towards our throat. Usually at night and in our sleep we cough or clear our throat and swallow this mucous. Yuk, but keeps our lungs clean.
What sort of cell? Single celled organisms have many types. Human's have many different cells a few with types of 'hair'. Cillia on the cells lining the lungs for example.
Cillia cells (hair) cells 'beat', encouraging the movement of objects/obstructions. Mucous doesn't necessarily get 'Swept around'. It is secreted by epithelial cells-- cells which line the respiratory tracts, the reproductory tracts and there's another I always forget the last thing.
cillia and mucus are best friends in the foot and work together to keep your big toe attached cillia and mucus are best friends in the foot and work together to keep your big toe attached
