Mucus traps solid particles that have made it into the trachea so that the ciliated cells on the wall of the trachea can use their periodic beating motion to gradually move the trapped particles up for clearance.
The epithelium cells in the trachea are of two types-one of which secretes mucus which traps particulate matters(particles carried by the inhaled air,and the other bears cilia which moves the thin layer of the mucus.
The function of mucus is to produce a "blanket" that carries debri and pathogens (disease causing microorganisms like bacteria and viruses) out of the respiratory tract with the action of cilia. Cilia are finger-like projections of the plasma membranes of pseuostratified columnar epithelial cells that make up the lining of the respiratory tract.
to keep all of the bad things from going in and in more precice terms
sticking to the nose hairs and caching dust particles and also when you have a runny nose when your sick it's because the bacteria are coming out inside the snot.
Mucous in the nasal cavity helps to keep dirt, and bacterium from invading the respiratory system, and iit helps to moisten the air as you breathe in. It also keeps the nasal passages from drying out.
Mucus traps the foreign particles. Cilia push the foreign particles out wards. This helps to protect your lungs from damage by the particles.
Cilia trap particles like bacteria and viruses, the cilia sweep in an upward direction. The mucus moves up to the pharynx where it is either coughed out or swallowed.
Mucus secreted by goblet cells trap the foreign particles. Cilia push the particles out wards. This protects your lungs from damage by the foreign particles.
Mucus and cilia are usually found in your airway passage. They function to clean the air that you breathe in for dust particles and other substances that would be harmful for your lungs.
to keep the stomach from digesting itself
The trachea.
Short, hair like appendages help in fastening to mucous membranes. These numerous appendages are called fimbriae. Cilia are another short, hair like appendage that extends from living cell surfaces.
The trachea is lined with ciliated columnar epithelium, which has hundreds of tiny hairs called cilia.
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.
The purpose of cilia and mucous membranes in your nose are to filter out and trap particulates, fibers and microorganisms (bacteria, etc.) in the air that is breathed in - then move that mucus containing the filterables to the back of the throat for swallowing or spitting out.
Mucous membranes and cilia in the trachea trap and eliminate particulate matter from inhaled air. The membranes also warm and moisten incoming air.
trachea
Mucous, made by mucous glands, stick to the cilia of cells that are found in the mucous membranes.
cilia
The trachea.
The combination of cilia and mucous helps to filter out solid particles from the air.
mucous membranes, cilia
These are tiny "fingers" which move mucous. The mucous is sticky and traps dust, pollen and other particles. Together the cilia move the mucous out of the lungs. If this didn't happen these things trapped in the mucous would cause damage to the lungs and a person would have breathing difficulties over time.
Little hairs called Cilia, which help filter dust from the air as it passes into the lungs.
The air passes through the NOSE, which has mucus membranes that clean/moiston air, as well as hairs (cilia) that attach to dirt and dust particles to keep them out of the rest of the respiratory tract.Final Answer: Nose
The trachea is lined with a moist mucous-membrane layer made up of cells containing small hairs called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous-membrane that secrete mucus droplets and water molecules.Cilia are whiplike, motile cellular extensions that occur, typically in large numbers, on exposed surfaces of certain cells. In the trachea, ciliated cells that line the respiratory tract propel mucus laden with dust particle and bacteria upward away from the lungs. Centrioles, referred to as basal bodies, are the originating source of cilia.
Short, hair like appendages help in fastening to mucous membranes. These numerous appendages are called fimbriae. Cilia are another short, hair like appendage that extends from living cell surfaces.
