Pseudo stratified columnar with goblet cells
Pseudostratified columnar epithelium
Yes. The Cilia do this so that we can prevent illness and the clogging up of unwanted materials (like dust) in the lungs, which may prevent from working to its full potential.

Simple columnar epithelium
bronchioles of lungs
Mucus is a sticky substance. Describe how mucus and cilia keep the lungs free of bacteria and dust particles.
some cells in this lining secrete a sticky liquid called mucus, which traps particles of dirt or bacteria that are breathed in. Other cells are covered with timy hair-like structures called cilia. It sweeps the mucus and trapped particles out toward the mouth.
because it has to trap all dust particles that didn't get trapped when going through nose and mouth...... by epidemic skate shop
Some cells that are found in the upper and lower respiratory tract have tiny hairs called cilia on them. They are found in the lungs, respiratory tract and middle ear. These cilia have a rhythmic waving or beating motion. They work, in this case, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation.
In unicellular organisms cilia are usually responsible for moving the organism around. In the human lung cilia are responsible for sweeping up the mucus that has collected dust particles and removing it from the lung. They have many other uses in other organisms also.

The cilia are tiny hairs which act to trap dust or dirt particles in the air that people breathe. The cilia and the mucus helps to keep dust and dirt out of the lungs.
Mucus is produced by the goblet cells, in the airways dust particles etc will stick to the mucus, cilia cells then use energy to sweep the mucus up back up through the trachea, where we can swallow it and dust particles and pathogens etc can be broken down by enzymes in the stomach, or we can expell it by sneezing or coughing.
Mucus is a sticky substance. Describe how mucus and cilia keep the lungs free of bacteria and dust particles.
Mucus and cilia keep the lungs free from bacteria and dust particles by trapping dust so that it can be swallowed and broken down by the digestive system. Alternatively, dust and bacteria can be expelled when sneezing or coughing.
The hairs in the nose are there to stop dust particles being inhaled into the lungs. Dust combined with natural mucus - is what 'bogies' are formed from (sorry if you're eating !)
The cilia are always moving, bacteria or particles of dust trapped in the mucus are moved away by cilia. The cilia waft the mucus containing bacteria and dust up to the back of the throat, so that it doesn't block up the trachea and thus keeps it clean.
To keep it clean and free from dust particles. The cilia beat mucus up to the back of the throat where it is swallowed. Without it the mucus would stick and act as a breaking ground for bacteria and fungus.
some cells in this lining secrete a sticky liquid called mucus, which traps particles of dirt or bacteria that are breathed in. Other cells are covered with timy hair-like structures called cilia. It sweeps the mucus and trapped particles out toward the mouth.
cilia transport mucus and other foreign substances such as dust and dander.
Airway motile cilia move mucus out of the lungs, and mucus traps inhaled particulate, smoke and dust.
yooo
