Flashcards in Respiratory System Review Deck (43):
1

in the nasal cavity, air passes over the ___

conchae

2

the nasal cavity is separated from the oral cavity by the ____

palate

3

the nasal cavity and the oral cavity join to the form the ___

pharynx

4

the inferior openings of the pharynx open into the __ and ___

larynx, esophagus

5

the opening from the pharynx into the respiratory passages is the __

glottis

6

the glottis can be covered by the

epiglottis

7

the trachea is held open by rings of

cartilage

8

the trachea divides into 2 __ ___

primary bronchi

9

after several branchings, the bronchi lead into ___

bronchioles

10

the bronchioles lead into the structures where gas is exchanged, called ___

alveoi

11

mucus and watery secretions are produced by __ cells and seromucus glands

goblet

12

these fluids along w/ foreign particles are normally moved out of the air passages by the organized beating of the __

cilia

13

the walls of bronchioles contain __ muscle and __ connective tissue

smooth, elastic

14

the mouth of the alveolus is shaped by a ring of __ tissue

elastic connective

15

this smooth muscle and elastic connective tissue helps the respiratory passages change shape with the ebb and flow of __

air

16

the epithelial cells (type 1) of the alveolus are ___ (tissue type).

simple squamous

17

type 1 cells are closely connected to the endothelium of ___

capillaries

18

type 1 cells provide for ___ exchange with the blood

gas

19

the surfactant prevents the surface tension of the water from causing the collapse of the ___

alveoli

20

the fluid allows the diffusion of ___ acros the respiratory membrane

gases

21

the bones surrounding the thoracic cavity are the ___, ___, and ___.

ribs, sternum, vertebrae

22

the thoracic cavity is separated from the abdominal cavity by a muscle called the __

diaphragm

23

the major organs found in the thoracic cavity are the __ and ___

heart, lungs

24

the outer surface of the lungs is covered by a membrane called the __

visceral pleura

25

the inner surface of the thoracic cavity is covered by a similar membrane called the __

parietal pleura

26

these serous membranes produce a watery fluid that allows the lungs to ___ within the thoracic cavity

expand

27

the (potential) space between the pleura is the __

pleural cavity

28

respiratory muscles found btwn the ribs are the __

intercostal muscles

29

after exhaling, a person at rest has a lung volume called __

Functional Residual Capacity (FRC)

30

since this lung volume occurs from passive relaxation of muscles, does the body have to expend metabolic energy to arrive at it?

no

31

the volume of resting inhalation described as 1 normal breath is called ____

tidal volume (TV)

32

By using extra muscular force, the lungs can be enlarged to a greater volume than tidal. this reserve is called __ volume

Inspiratory Reserve Volume (IRV)

33

when the lungs are at FRC, extra muscular force can cause lung volume to decrease expelling additional air. This reserve is called ___ volume

Expiratory Reserve Volume (ERV)

34

the total volume change that the lung can accomplish is called the __

Vital Capacity (VC)

35

When the thorax has forcefully expelled as much air as possible, the lungs are not completely empty. Their volume is called the ___

Residual Volume (RV)

36

When the diaphragm contracts, its central tendon is pulled inferiorly, causing the volume of the thoracic cavity to ___

increase

37

when the external intercostal muscles contract, the ribs pivot in a ___ direction. This causes the anterior-posterior dimension of the thorax to ___.

superior, increase

38

these 2 changes cause the total volume of the thoracic cavity to __

increase

39

since the volume of the thoracic cavity have increased, the pressure within it has ___

decreased

40

if the pressure in the thorax falls below atmospheric pressure, the air moves ____ the lungs

into

41

when the diaphragm relaxes, the abdominal pressure causes the central tendon to move back toward the thorax , the thoracic pressure __

increases

42

when the external intercostal muscles relax, the ribs falls back to their resting position, causing the anterior-posterior dimension of the thorax to ___.

decrease

43

These changes ___ the pressure on the air, causing it to move ___ the lungs

increase, out of
