Flashcards in Lecture 8 Deck (27):
1

What are the subsystems of speech production? 

Neural

respiratory

laryngeal

articulatory

2

What are the structures of the airway system?

upper airway larynx lower airway

3

What are the functions of the upper airway? 

warms air  humidifies air  filters the air conducts air to the lung (enterance)  speech articulation- resonance

4

What are the structures of the upper airway?

oral cavity nasal cavity pharyngeal cavity

5

What is in in the oral cavity? 

mouth lips teeth  tongue

6

Why is the nose the preferred breathing method? 

becasue it filter the air and warms the incoming air --> warms it through membranes that line the nose and contain lots of blood vessels

7

What is included in the Pharyngeal cavity?

nasopharynx oropharynx laryngopharynx

8

What are the functions of the larynx? 

to act as a valve to protect the airway throacic fixation: in teh lungs and in the abdominal cavity used for bodily functions such as urination, defacation, child birth and vomiting speech phonation, allows for phonation

9

What are the structures of the larynx? 

cartilage  muscle

10

What are the functions of the lower airway

filters the air site of gas exchange power source for spech via build up of sbuglottal pressure

11

What are the structures in the lower airway? 

trachea

bonchi and bronchioles

alveoli

lungs

pleura

12

where does the trachea branch into the bronchi? 

at the carina

13

What are pseudostriatified ciliated columnar epithelium? 

cilia beat down quickly and slow upward at about 10/sec coninuously in motion these rid us of accumulated mucous, particles and dust --gets things ot the larynx then we can then cough it up 

14

what do the bronchi and bronchioles do? 

give us flexibility and motion ot maintain our airway extends from the trachea into the alveoli of the lungs impomplete carilaginous rings of decreasing diameter with increasinly more smooth muscles forms an arborized tree lik system 

15

What are bronchi? 

larger diameter passages outside and immediately inside the lungs 

16

What are the bronchioles? 

they appear after abou thte 24th division of the bronchi inside the lungs they get smaller and smaller in diameter with greater and greater surface area they have less and aless cartilage and more and more smc ending at the terminal bronchioles they (bronchioles) communicate with the alveolar air sacs

17

What are the two types of Alveoli? 

Type I - this is the epitheolial cell lining Type II- these produce surfactant which reduces the surface tension of fluids in teh alveoli 

18

What are the phagocyte cells

they destroy and break down debris

19

Are the lungs made of active or inactive tissue? 

inactive tissue

20

How many lobes does the right side of the lung have?  How many lobes does the left side of the lung have? 

Right = 3 Left =2

21

What is the top of the lungs called?  What is the bottm of the lungs called? 

Top = Apex Bottom = Base

22

What are pleural membranes? 

they encase the lungs in a moist (serous), airtight membrane that adheres to the lungs and one adheres to the chest wall

23

What is the visceral (pulmonary) pleura

lines the outside of the lungs

24

What is the parietal (costal) pleura

attached to the chest wal/ rib cage

25

What is the visceral pleura

attached to the outside of the lungs, outside surface of lung continuous with parietal pleura

26

What is trauma to the lungs called? 

pneumothorax

27

What does the pleural linkage do? 

Connects the visceral and parietal pleura due to surface tension of the fluid in the intrapleural space and negative intrapleural pressure

keeps lungs from deflating

lungs move with the chest wall in motion
