Flashcards in Respiratory System Deck (37):
1

What makes up the upper respiratory system?

Nose, nasal cavity, paranasal sinuses, pharynx

2

What makes up the lower respiratory system?

Larynx, trachea, bronchus, bronchioles, smallest bronchioles, alveoli

3

Respiratory portion of the tract consist of

smallest bronchioles, alveoli

4

Conducting portion of the tract consist of

Nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, bronchus, bronchioles

5

What is the function of the upper respiratory system

The upper respiratory system filters, warms and humidifies incoming air (all of which protects the delicate surfaces of the lower respiratory system) and resorbs heat and water from outgoing air.

6

What is the function of the lower respiratory system?

The lower respiratory system conducts air to and from gas exchange surfaces

7

Constant movement of ____ sweeps mucus and debris toward the pharynx where they will be either coughed out or swallowed

cilia

8

What 2 things clean and protect respiratory surfaces

Ciliary movement and mucus

9

What is lamina propria?

Loose connective tissue providing support to the overlying epithelium; contains mucus glands

10

What is another name for a mucous cell

Goblet cell

11

The respiratory mucosa is an epithelium that lines the conducting portion of the respiratory tract. It is a ______________________________

ciliated pseudostratified columnar epithelium

12

What do goblet cells produce?

Goblet cells produce a sticky mucus that bathes and protects exposed surfaces

13

What type of epithelium lines the pharynx

The pharynx is lined with a stratified squamous epithelium to protect it against abrasion

14

What type of epithelium is found in narrower respiratory passages?

Cuboidal epithelium

15

The histological structure of the respiratory epithelium changes dramatically along the entire length of the respiratory tract.

The histological structure of the respiratory epithelium changes dramatically along the entire length of the respiratory tract.

16

What is the primary passageway for air entering the respiratory system?

Nose

17

What does air do after it enters the nose?

Air swirls around conchae and particles become trapped in mucus. Air also becomes warmed and humidified.

18

The _____ is shared by the respiratory and digestive systems.

Pharynx

19

The __________ extends from the posterior part of the nasal cavity to the soft palate

nasopharynx

20

The _________ extends between the soft palate and the base of the tongue at the level of the hyoid bone

oropharynx

21

The __________ extends between the hyoid bone and the entrance to the larynx

laryngopharynx

22

What is the actual name of the "voice box"

larynx

23

What are the 2 large cartilages that make up the larynx

Thyroid and cricoid cartilage

24

What is the larynx made up of?

Cartilage

25

What is thyroid cartilage

Thyroid cartilage – forms the laryngeal prominence or Adam’s apple. It is attached by a ligament to the hyoid bone.

26

What is cricoid cartilage

Cricoid cartilage – a ring of cartilage inferior to the thyroid cartilage.

27

What is the epiglottis?

Epiglottis – forms a lid over the larynx; during swallowing the epiglottis folds back over the larynx and prevents food and liquid from entering the respiratory tract.
It is the fold preventing food to go down the wrong hole.

28

What is the vocal ligament?

elastic ligament within the vocal fold (true vocal cords) that vibrates and produces phonation (sound production at the larynx).

29

What is the difference of intrapulmonary and extrapulmonary?

extrapulmonary (outside the lungs)
intrapulmonary (inside the lungs)

30

How many lobes are in the right lung?

3

31

How many lobes are in the left lung?

2

32

The trachea’s rings of cartilage stiffen its wall and protect the airway.

The trachea’s rings of cartilage stiffen its wall and protect the airway.

33

What are the pleural cavities?

The right and left pleural cavities that house the lungs are formed similarly to the pericardial cavity that houses the heart.

34

What are the fissures called that separate the lobes of the lungs

Oblique-vertical
Horizontal-horizontal

35

Where does air flow in the lower respiratory tract?

Trachea
-primary bronchi
-secondary bronchi
-tertiary bronchi
-bronchioles
-terminal bronchioles to pulmonary lobules

36

The respiratory ________ marks the start of the respiratory portion of the tract in which gas exchange can occur.

bronchiole

37

A _______ is an air sac, across the wall of which exchange of gases occurs

alveolus
