—Bronchi, bronchioles and alveoli - looks like an upside down tree.
◦Trachea is the main trunk that divides into
◦Right bronchus and left bronchus. As the bronchi enter the lungs they divide into smaller and smaller branches.
◦The smallest tubes whose walls are made only of smooth muscle are called bronchioles.
◦Bronchioles further divide into microscopic tubes called alveolar ducts which resemble the main stem of a bunch of grapes.
◦Alveolar ducts end in several alveolar sacs arranged like a clusters of grapes.
◦The walls of the alveolar sacs are made up of numerous alveoli each of which resembles a single grape.

Ciliated simple columnar epithelium is found in the?
Ciliated simple columnar epithelium is found in the lining of the fallopian tubes, bronchioles of the respiratory tract, and parts of the gastrointestinal tract such as the stomach and intestines. This type of epithelium helps in moving mucus and particles along the surface of these organs.
What are the two major parts of the respiratory system?
The two major parts of the respiratory system are the upper respiratory tract, which includes the nose, nasal cavity, pharynx, and larynx, and the lower respiratory tract, which includes the trachea, bronchial tubes, bronchioles, and lungs.
What is bronchial secretions?
Bronchial secretions are fluids that are produced by the cells lining the bronchial tubes in the respiratory tract. These secretions help to keep the airways moist, trap foreign particles, and assist in clearing mucus and debris from the lungs through coughing or swallowing. Changes in the amount or composition of bronchial secretions can occur in various respiratory conditions.
What are facts about Ciliated epithelium?
Ciliated epithelium is a type of tissue in the human body that contains hair-like structures called cilia. These cilia help move substances along the surface of the tissue, such as mucus in the respiratory tract. Ciliated epithelium is found in areas like the respiratory tract, fallopian tubes, and parts of the brain.
Where is ciliated epithelium reflected in its arrangement?
Ciliated epithelium is found in areas where movement of particles, such as mucus and debris, is important. It is commonly found in the respiratory tract, fallopian tubes, and parts of the reproductive system. The cilia help to move substances along the surface of the epithelium.
Tissue that lines respiratory tract and fallopian tubes?
Simple columnar epithelial
What is the smallest conducting passageways of the lungs are called?

Is pharynx part of the upper respiratory tract?
Yes they are. They are all connected by pesky tubes that can clog up at a moments notice and an infection in one can often end up as an infection in the other.
Where is the trachea found upper and lower part of the respiratory tract?
the upper part of trachea is larynx and lower is two tubes which are bronchi
Which of the following is not true of the respiratory tract from the medium bronchi to the aveoli?
lining of the tubes changes from ciliated columnar to simple squamous epithelium in the alveoli
What is pulmuno?
Pulmonology is a sub-specialty of internal medicine. Pulmonologists are doctors that are specialists of the lower respiratory tract, that include the lungs and bronchial tubes.
How does the bronchi work?
A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
What parts are in the lower respiratory tract?
The main parts of the lower respiratory tract are the trachea, two bronchial tubes, the bronchioles, and the lungs. The upper and lower respiratory tracts come together to make up the entire respiratory system.
What is the special cell that lines the tubes in the respiratory system?
Goblet cells are found in the respiratory epithelium. They produce mucous which coats the tubes. Goblet cells are found scattered among the epithelial lining of organs, such as the intestinal and respiratory tracts. They are found inside the trachea, bronchi, and larger bronchioles in the respiratory tract, small intestines, the large intestine, and conjunctiva in the upper eyelid.
What are the smallest divisions from the trachea?
The division of the Trachea is the Bronchial Tubes.
What are the functions of the respiratory tract?
The respiratory tracts holds the function of allowing a person to breathe by supplying oxygen to all parts of the body. It is made up of airway paths, which include the nose, voice box, mouth, windpipe and bronchial tubes.
Is the bronchi branch into smaller tubes called cilia?
