19
Q

Occupy 97% of the total alveolar surface

A

Type I alveolar cells or type I pneumocytes or squamous alveolar cells

20
Q

Commonly located near the angles between neighboring alveolar septa
Synthesize and secrete pulmonary surfactant

A

Type II alveolar cells or type II pneumocyte

21
Q

2 Types of Epithelium Alveoli

A

Type I alveolar cells or type I pneumocytes or squamous alveolar cells
Type II alveolar cells or type II pneumocyte

22
Q

Septa between adjacent alveoli contain a dense network of capillaries supported by collagenous and elastic fibers

A

Alveoli

23
Q

Small openings, the alveolar pores (pores of Kohn) provide communications between alveoli

A

Alveoli

24
Q

Epithelium is made up of 2 cell types

A

Alveoli

25
Q

Thin-walled saccular compartments

A

Alveoli

26
Q

Where exchange of oxygen and carbon dioxide takes place between the blood and the inspired air

A

Alveoli

27
Q

Estimates of the number of alveoli in the 2 human lungs is 300 million

A

Alveoli

28
Q

Terminal bronchioles end in

A

Alveoli

29
Q

Respiratory bronchioles

A

alveolar ducts

30
Q

Alveoli are so numerous
At the end of the duct, there are clusters of 4 or more alveoli

A

Alveolar Ducts

31
Q

Bifurcation of the terminal bronchioles gives rise to respiratory bronchioles

A

Respiratory Bronchioles

32
Q

Columnar with rounded apex,
Cells with apical secretory granules
Secrete proteins that protect the bronchiolar lining against oxidative pollutants and inflammation; also secrete surfactant

A

Clara cells

33
Q

Goblet cells are no longer present at the level of the bronchioles
Ciliated pseudostratified columnar cells
In the terminal bronchiole
Epithelium also contains nonciliated cells, called Clara cells

A

Bronchioles

34
Q

The 12th to 15th generations of branching of the bronchial tree
Diameter of 5 mm or less
No cartilage plates in their wall
No glands in the lamina propria
Smooth muscle does not form a continuous circumferential layer but are seen as discrete bundles of varying orientation

A

Bronchioles

35
Q

Ciliated columnar epithelium
Height of the epithelium gradually decreases along the tract, becoming sparsely ciliate cuboidal epithelium in the bronchioles and low cuboidal in the terminal bronchioles

A

Bronchial epithelium

36
Q

As cartilage in the wall diminishes, smooth muscle becomes more prominent

A

Bronchi

37
Q

Very similar to that of the trachea up to the point where they enter the lungs
As it enters the lungs, the cartilage rings are replaced by cartilage plates of irregular outline
Intrapulmonary bronchi are therefore cylindrical not flattened posteriorly

A

Bronchi

38
Q

Posterior wall
Band of transversely oriented smooth muscles

A

Trachea

39
Q

Lined by a ciliated pseudostratified columnar epithelium with numerous goblet cells

A

Trachea

40
Q

Flexible tube about 11 cm long and 2 cm in diameter

A

Trachea

41
Q

Ventral and lateral walls
Encircled by a series of 16 – 20 C-shaped hyaline cartilages

A

Trachea

42
Q

thyroid and cricoid hyaline cartilages
a thin leaf of fibroelastic cartilage, the epiglottis, that projects obliquely, upward and backward, over the lumen

A

Wall is made up of LARYNX

43
Q

the upper pair are called the vestibular folds (false vocal cords)
the lower pair are the vocal folds or true vocal cords

A

2 folds of the mucosa of larynx

44
Q

Anterior surface of the epiglottis and the vocal folds are covered by

A

stratified squamous epithelium

45
Q

All the rest of the lining of the larynx is

A

ciliated pseudostratified epithelium
