25
Q

Pathway of air

A

Mouth/Nose->Pharynx->Larynx->Trachea->Bronchi->Bronchioles->Alveoli

26
Q

gas exchange

A

oxygen enters blood and carbon dioxide leaves

27
Q

Where does gas exchange occur?

A

Alveoli

28
Q

lungs are surrounded by

A

pleural membranes (visceral and parietal)

29
Q

Pharynx

A

Throat,
nasopharynx, oropharynx, and laryngopharynx.

30
Q

Larynx

A

voice box, thyroid and cricoid cartilage

31
Q

Trachea

A

windpipe

smooth muscle: goblet cells and cilia

cartilage

32
Q

Bronchi

A

primary, second, tertiary

33
Q

Bronchioles

A

no cartilage

smooth and elastic tissue

constricts and dilates

terminal bronchiole- leads to alveoli

34
Q

Diseases that constrict air flow

A

COPD

35
Q

Emphysema

A

destruction of lung issue

36
Q

Asthma

A

dysfunctional immune response

37
Q

Alveoli

A

simple squamous epithelium

where gas exchange occurs

covered in surfactant

38
Q

upper respiratory tract

A

consists of the nose, mouth, pharynx, epiglottis, larynx, and trachea

39
Q

lower respiratory tract

A

larynx, trachea, bronchi, lungs

40
Q

Tidal volume

A

Amount of air that moves in and out of the lungs

41
Q

Residual capacity

A

Amount of air remaining in the lungs after exhalation

42
Q

inspiration

A

breathing in (inhalation)

43
Q

expiration

A

breathing out (exhalation)

44
Q

What happens during inspiration?

A

the diaphragm contracts, lungs expand and intra-alveolar pressure decreases, thoracic pressure increases

45
Q

what happens during expiration?

A

diaphragm and external intercostal muscles relax, decrease thorax pressure and increase lung pressure

46
Q

Where does ventilation occur?

A

diaphragm, intercostal muscles, pressure change

O2 in CO2 out

47
Q

Factors affecting diffusion in gas exchange?

A

Concentration gradient

Surface area

Distance
