In the lining of the trachea, bronchi, and bronchioles.
The respiratory system contains mucous and tiny hairs called cilia. These are primarily found in the trachea and bronchi to help remove dust, debris, and pathogens from the airways.
The bronchi are located in the lungs and are coated with mucus. They also have cilia which are small hair-like projections on the surface of the bronchi that move the mucus towards the outside of the body.
two like structures that lead to the lungs and branch off into the broncoe. (trachea) The two main bronchi are formed when the trachea (or windpipe) divides. The right bronchus is more vertical than the left. It is also wider and shorter. It is approximately 2.5cm in length and after entering the right lung it divides into three branches (one going to each of the three lobes of the right lung). Each branch then divides into many smaller branches. As the bronchi get smaller, they are called bronchioles. Bronchioles become terminal bronchioles, then respiratory bronchioles, alveolar ducts.. and finally alveoli. The left bronchus is about 5cm in length and is narrower than the right. After entering the left lung, it divides into two branches (one for each of the two lobes of the left lung). Each branch then divides into smaller bronchi in the same way as the bronchi in the right lung, ending in the alveoli. The bronchi are lined with ciliated columnar epithelium. This contains cilia which are hair like extensions that propel materials along the airways. This helps to keep the airways clear.
ether the cilia, pharynx or the bronchi
The alveoli is found at the end of each Bronchiole and Bronchi. The alveoli gets rid of all the carbon dioxide that is in our lungs.If you need more help just ask another question and I'll be free to answer it.
The cilia of the primary bronchi mucosa functions by beating upward towards the larynx. As such, they conduct air into both lungs.
Cilia are responsible for removing foreign material from the trachea and bronchi. They are like little dusters that remove germs and bacteria.
Only some flatworms, usually the smaller species, have small "hairs" called cilia on their skin.
Air gets warmed and cleaned as it passes through the nasal cavity, where it is humidified, filtered, and warmed by the mucus and tiny hairs called cilia. Additionally, the air is further warmed and cleaned in the trachea and bronchi by the same mechanisms of mucus and cilia before reaching the lungs.
