Flashcards in The respiratory system Deck (56):
1

What are the sizes of airflows

Bronchi to bronchioles to alveoli

2

What is the boundary between upper and lower respiratory tract?

The vocal cords

3

What kinds of cartilage is the septal cartilage?

Hyaline cartilage

4

What is the common name for the anterior (exterior) naris?

The Nostril

5

What are the three jobs of the upper respiratory tract?

Warm, Humidify and filter the air

6

What is the purpose of Nasal Conchae (nasal terminate bones)

To create turbulance to warm filter and humidify the air

7

What type of cartilage is the epiglotis? How does it actually close off the airway?

elastic. The trachea rises to it

8

Regions of the pharynx

Nasopharynx, orophaynx

9

What is the largest of the cartilage

Thyroid cartilage

10

What is the limiting cartilage of what can find down the windpipe?

the Cricoid cartilage which is the only piece of cartilage that is a complete circle

11

Bottom of the trachea before it starts to branch is called

carina. It contains mecano-receptors that cause coughing

12

which primary bronchi is larger and more likely to get stuff large?

the right side because it is larger and mor vertical

13

secondary bronchi

One for each lobe of the lung. Two on the left three on the right

14

What kind of epithelium do the respiratory bronchioles have?

.simple squamous epithelium

15

What is the shape of the primary bronchials?

C shaped - like trachia

16

What is the shape of the secondary bronchials?

.

17

pseudo-stratified columnar epithelium

.

18

What is the purpose of the surfactant in your lungs and where is it produced?

It decrease the surface tension for the alveolai. Produce by the septal cells

19

What are the steps of inhilation?

Ventalation, inspiration, resistance to airflow, ff, fff,

20

How does air move into the lungs?

The a pressure

21

760 Torr (mL of mercury) = 1 atm

Atmospheric pressure is

22

What is filling the the pleural cavity and what are its two main function?

It is filled Serous Fluid. It is for lubrication and to create adhesion to the thoracic muscles.

23

What is Boyle's Law?

P1V1 = P2V2

24

What are the medicines given for asthma and why?

sympathetic mimics?

25

Beathing patterns

..

26

What is Eupnea?

Normal or quiet breathing

27

What is Tachypnea?

Rapid breathing

28

What isDyspnea?

difficult or labored breathing

29

What are secondary effects of COPD

high blood pressure, heart disease

30

How does smoking impact respiratory effiency?

-nicotine vaos-constricts, carbon monoixde binds hemoglon, .........

31

What is the effect of nicotine on the airway?

It is a vasoconstrictor

32

Lung cancer ( by smoaking

bronchial epithelium into stratified squamous

33

Describes the origin and pathology of small cell (oat cell carcinoma

The originate in the primary bronchi

34

What are secondary effects of COPD

high blood pressure, heart disease

35

How does smoking impact respiratory effiency?

-nicotine vaos-constricts, carbon monoixde binds hemoglon, .........

36

What is the effect of nicotine on the airway?

It is a vasoconstrictor

37

Lung cancer ( by smoaking

bronchial epithelium into stratified squamous

38

Describes the origin and pathology of small cell (oat cell carcinoma

The originate in the primary bronchi

39

What is the conducting division respiratory system?

The "pipes" nostrils, pharynx, trachea, bronchi, bronchioles, including terminal bronchioles

40

What are two cartilage areas of the nose?

The septal cartilage and the alar cartilage

41

What are the macrophages of the lungs called?

Alveloar dust cells

42

What is Dalton's law?

Partial prssures....

43

People (probably all land animals) are _____ pressure breathers. This means that we ____ the volume of our lungs in order to ____ the pressure to draw air in.

Negative pressure breathers. Increase the volume, to lower the pressure .

44

What is Charle's law? How does it relate to breathing?

if you heat a gas under constant pressure the volume will expand. Warm the air in the body help the volume expand more

45

Dalton's Law

The partial pressure of each gas equals to total pressures or 1 atm

46

Henri's law

The amount of a gas going into the blood depends on its soluabillity

47

What part of respiration typically does muscular work?

Inhalation

48

What cause exhalation to occur without muscular work

Surface tension of water colapsing alveoli and pulling thoracic cavity in with the lungs

49

What is a pneumothorax? What is the effect on respiration and by what mechanism?

A pneumothorax is additional air in the pleural cavity, often a wound, but they can be spontaneous. The cause lung to collapse because the intrapleural pressure is now equal to or greater than the pressure in the lungs.

50

What is compliance of the lung?

The elasticity of the lung

51

What is the valsalva maneuver?

Holding air in you lungs to add pressure to help with abdominal work

52

What is the Dorsal respiratory group?

Part of the medulla that control baseline respiration. As called the inspiratory area

53

What does the ventral respiratory do?

Controls the muscles for forced exhalation. The internal intercostals and the abdominal muscles

54

What do the Pneumotaxic and apneustic areas do?

Pneumatic increases respiration. Apneustic is decreased breathing during deep sleep. They are also called the pontine respiratory group

55

Where is pH monitored in the body ? Are the differences at the different locations?

In the medulla, caratoid sinuses, and the aortic arch. The medulla measure CSF and primarily measures protons and secondarily CO2. The arteries measure blood, the measure C02 primarily and protons secondarily.

56

What is hypercapnea?

too high partial pressure of CO2.
