regulation of lumen; has fibroelastic ligament for prevention of over distension of trachea
28
Closed cavities in the frontal, maxillary, ethmoid and sphenoid bones
Paranasal Sinus
29
(Trachea or Bronchus) Smooth muscle characteristics: Spanning open ends of c-shaped rings
Trachea
30
Separates one alveoli from another alveoli
alveolar wall/Inter-alveolar Septum
31
Epiglottis (function)
that prevents food and fluid from entering airway passages
32
Function to equalize air pressure between adjacent alveoli and promote collateral circulation of air
Alveolar Pores/Pores of Kohn
33
Type of respiratory cells that secrete hormones and are part of the diffused endocrine system Resembles basal cells but with numerous granules with dense cores
Small granule cells/ Kulchitsky cells
34
Number of C Shaped hyaline cartilage in Lamina Propia of the Trachea?
16-20 C Shape hyaline cartilages rings
35

Bowman's gland/Olfactory gland
36
Hyaline cartilage in Trachea (Function)
Keeps tracheal lumen open
37
Respiratory cells that function as generative stem cells and undergo cell division when needed Small rounded cells that lie on basal lamina
Basal Cells
38
Relaxation of the Trachaealis: (Increases or Decreases) the diameter
Increases
39
(Trachea or Bronchus) Location of cartilage: Anterior Part
Trachea
40
Nasopharynx (Function)
conduct, warm and moisten inspired air
41
In between layers of the alveolar wall that is full of capillaries and connective tissues. It is the richest capillary network of the body
Intersitium
42
found in lamina propria thick short hairs with sebaceous and sweat glands that filter out large particles from the inspired air
Vibrissae
43
Vocal Cord (lining)
non-keratinized stratified squamous epithelium
44
Clara Cells (Function)
secretes surfactant to lower the surface tension to prevent sticking of the walls of the alveoli during expiration. Also functions as stem cells to replace the injured epithelial cells. For detoxification and secretes antimicrobial peptides
45
Three parts of the Pharynx
Nasopharynx, Oropharynx, Laryngopharynx
46
Respiratory portion that provides conduit for movement of air to and from the lungs conditions inspired air

Trachealis Muscle
55
True Vocal Cord, lower fold
Vocal Fold/ Cord
56
