The changing epithelial cells along the respiratory tree are specialized to perform different functions. For example, the ciliated pseudostratified columnar epithelium in the trachea and bronchi helps to move mucus and trapped particles out of the airways, while the simple squamous epithelium in the alveoli facilitates gas exchange. This specialization allows the respiratory system to efficiently carry out its functions of breathing and gas exchange.
What else can I help you with?
What cellular organelle is a projection that moves substances onto epithelial surfaces?
Cilia are cellular projections that move substances along the surface of epithelial cells. They beat in a coordinated manner to propel mucus and other substances across the epithelial surface, aiding in functions such as mucus clearance in the respiratory tract.
Is a celiated epithelial cell a part of an animal or plant?
Ciliated epithelial cells are usually found in animals. They are involved in movement and transportation of mucus or other substances along surfaces in organs such as the respiratory tract and reproductive system. Plants do not possess ciliated epithelial cells.
What type of epithelium are found in the nasopharynx?
The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
What does the ciliated epithelium cell produce?
Ciliated epithelial cells produce mucus, which helps to trap and remove foreign particles and pathogens from the respiratory tract. The cilia on the cell's surface then move the mucus along to be expelled or swallowed.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.

The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
Which cells are tall and rectangular and have cilia?
Columnar epithelial cells are tall and rectangular and may have cilia on their surface for movement of substances like mucus along the respiratory tract or oviduct.
What does the ciliated epithelium cell produce?
Ciliated epithelial cells produce mucus, which helps to trap and remove foreign particles and pathogens from the respiratory tract. The cilia on the cell's surface then move the mucus along to be expelled or swallowed.
What are the motile cellular extensions found in large numbers in some epithelial cells called?
Cilia are the motile cellular extensions found in large numbers in some epithelial cells. These hair-like structures help move fluid and particles along the cell surface, aiding in processes such as mucociliary clearance in the respiratory tract.
How are cilated epithelial cells adapted for their job?
Ciliated epithelial cells are adapted for their job of moving mucus and debris along surfaces within the body by having hair-like structures called cilia on their surface. These cilia beat in a coordinated fashion to create a sweeping motion that helps propel particles along. Additionally, ciliated epithelial cells are often found lining respiratory passages and the female reproductive system, where their movement helps maintain proper function and health.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.
What would would a group of ciliated cells be called?
ciliated epithelial tissue
Why do cilitated epithelial cells occur in large groups that form a tissue?
Ciliated epithelial cells occur in large groups to collectively move a layer of mucus and particles along a surface, such as in the respiratory tract or fallopian tubes. This coordinated movement helps to remove debris and pathogens from the body more efficiently than individual ciliated cells could achieve.
What is the respiratory membrane made of?
The Respiratory membrane: The wall of the alveoli are composed primarily of a single layer of squamous epithelial cells, called type I cells, surrounded by a flimsy basement membrane. See page 815 anatomy and physiology 8th
How is a ciliated epithelial cell modified?
A ciliated epithelial cell is modified with hair-like structures called cilia on its surface that help in moving substances along the cell surface. These cilia beat in a coordinated manner to generate a unidirectional flow of substances like mucus in the respiratory tract or egg in the fallopian tubes. The presence of cilia increases the surface area of the cell and enhances its function in moving materials efficiently.
