Adventitia

Located in esophagus. It replaces the serosa. Ordinary fibrous connective tissue that binds the esophagus to surrounding structures.

2

Adventitia

Outermost layer of the esophagus.

3

Mucosa

innermost layer of esophagus

4

submucosa

middle layer of esophagus

5

Type of tissue in esophagus

hyaline cartilage

6

The respiratory bronchioles lead into the

alveolar ducts

7

walls consist of diffusely arranged rings of smooth muscle cells, connective tissue fibers and outpocketing alveoli

alveolar ducts

8

thin walled air sacs

alveoli

9

Air is moved into and out of the lungs so the gases there are continuously changed and refreshed

pulmonary ventilation

10

oxygen diffused from the lungs to the blood, and carbon dioxide diffuses from the blood to the lungs

external respiration

11

oxygen is transported from the lungs to the tissues cells of the body, and carbon dioxide is transported from the tissue cells to the lungs.

transport of respiratory gases

12

oxygen diffuses from blood to tissue cells and carbon dioxide diffuses from tissue cells to blood

internal respiration

13

the actual use of oxygen and production of carbon dioxide by tissue cells is known as

cellular respiration

14

the two zones of the respiratory system

respiratory and conducting

15

actual site of gas exchange

respiratory zone

16

composed of the bronchioles, alveolar ducts and alveoli

respiratory zone

17

provide fairly rigid conduits for air to reach the gas exchange sites

conducting zone

18

cleanse, humidify and warm incoming air

conducting zone

19

Separates the nasal cavity from the oral cavity

palate

20

anteriorly, where the palate is supported by the palatine bones and processed of the maxillary bones

hard palate

21

the unsupported posterior portion of the palate

soft palate

22

the roof of the nasal cavity is formed by what two bones

ethmoid and sphenoid

23

connect pharynx to trachea. Has framework of cartilage and dense connective tissue.

larynx

24

air passageway, prevents food from entering lower respiratory tract

larynx

25

opening of the larynx

glottis

26

houses true vocal cords

larynx

27

flexible tube running from larynx and dividing inferiorly into two main bronchi.

trachea

28

walls contain C-shaped cartilages that are incomplete posteriorly where connected by trachealis

trachea

29

air passageway, cleans warms and moistens incoming air

trachea

30

main site of gas exchange

alveoli

31

serous membranes

pleurae

32

produce lubricating fluid and compartmentalize lungs

pleurae

33

located in the roof of the nasal cavity

olfactory epithelium

34

lines most of the nasal cavity

respiratory mucosa

35

pseudostratified ciliated columnar epithelium

respiratory mucosa

36

what does the respiratory mucosa contain

goblet cells

37

the groove inferior to each concha is the

nasal meatus

38

connects the nasal cavity and mouth superiorly to the larynx and esophagus inferiorly.

pharynx

39

posterior to the nasal cavity, inferior to the sphenoid bone, and superior to the level of the soft palate

nasopharynx

40

lies posterior to the oral cavity and is continuous with it through an archway called the isthmus of the fauces

oropharynx

41

the tonsils that lie embedded in the lateral walls of the oropharyngeal mucosa just posterior to the oral cavity

palatine tonsils

42

the tonsil that covers the posterior surface of the tongue

lingual tonsil

43

lies directly posterior to the upright epiglottis and extends to the larynx where the respiratory and digestive pathways diverge

laryngopharynx

44

the voice box

larynx

45

superiorly attaches to the hyoid bone and opens in the laryngopharynx. Inferiorly it is continuous with the trachea

larynx

46

provide a open airway, act as a switching mechanism to route air and food into the proper channels and house the vocal cords

larynx

47

cartilage of larynx

hyaline

48

inferior to the thyroid cartilage and is ring shaped

cricoid cartilage

49

cartilages that form the lateral and posterior walls of the larynx

arytenoid, cuneiform, and corniculate

50

the epiglottis is what kind of cartilage

elastic

51

the vocal folds and the medial opening between through which air passes are called

glottis

52

another name for the false vocal cords

vestibular folds

53

what kind of cells line the superior portion of the larynx

stratified squamous epithelium

54

the tracheal wall consists of what kind of cartilage

hyaline

55

the outmost layer of the connective tissue in the trachea

adventitia

56

which main bronchus is wider, shorter and more vertical

right

57

which side of the lung only has two lobes

left

58

secrete a fluid containing a detergent like substance called surfactant

type II alveolar cells

59
