What else can I help you with?
Cells lining the trachea have whiplike mortile extensions on their free surfaces What are their extensions what is their source and what is their function?
The whiplike motile extensions are called cilia. They are sourced from the basal body of the cell. The function of cilia in the trachea is to move mucus and trapped particles upward and out of the airway, helping to clear the respiratory tract.
What is the tube held open by rings of cartilage lined with cilia and mucous membrane?
The tube is known as the trachea, or windpipe. It serves as a passageway for air to travel in and out of the lungs. The rings of cartilage help keep the trachea open, while the cilia and mucous membrane function to trap and remove any foreign particles or debris from the air before it reaches the lungs.
What cells line the trachea?
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.
What is the trachea lined with to sweep away particles and dust?
The trachea is lined with cilia, which are tiny hair-like structures that beat in a coordinated manner to sweep away particles and dust trapped in mucus towards the throat where they can be expelled by coughing or swallowing.
What household item represents cilia?
A pipe cleaner can represent cilia. Cilia are hair-like structures found on the surface of some cells that help with movement and transportation of materials. Just like a pipe cleaner can bend and move, cilia can also bend and move to help cells function properly.
What is the protective function of the cilia and goblet cells of the trachea?
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.

The trachea is lined with what?
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.
What is the function of cell lining the trachea?
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.
What structure sweeps mucus and pathogens from the nasal cavities and trachea to the pharynx?
Beating ciliated epithelial cells

What types of tissue can have cilia?
The parts of the body that have ciliated columnar epithelium include the nose, the trachea, and the uterine tube. The cilia in the nose and trachea help expel foreign particles that should not enter the lungs while the cilia in the uterine tube help move the egg and sperm to the Fallopian tube.
How is the trachea adapted to its function?
yooo
What is a tube containing cilia called?
A tube containing cilia is called a trachea. The trachea is part of the respiratory system and it helps to move mucus and debris away from the lungs by the beating action of the cilia.
Smoker's cough results from damage to the external structure of lung cells by tobacco smoke What part of the cell would you predict is damaged?
Smoker's cough results from damage of the cells that line the trachea which have cilia. The cilia are damaged so that the mucus cannot be moved and therefore be swallowed. Coughing helps to remove the mucus. Also smoke irritates the cells of the trachea and produce the cough
What role do cilia play in respiration?
In mammals, the cilia in the airways (the bronchioles) move the mucus which traps the particles in the air (that you breath) up and out of the trachea and let it spill into the esophagus from where it is swallowed. i.e. its a cleaning function.
