Q

What does boyle’s law state?

A

That volume changes lead to pressure changes which then lead to the flow of gasses

18
Q

Describe expiration

A

It normally depends on lung elasticity, not muscle contraction

19
Q

What depends on lung elasticity?

A

Expiration

20
Q

Is breathing a positive or negative pressure system?

A

It’s a negative pressure ventilation system

21
Q

What do the pleurae in general do?

A

They keep the lungs from separating or sticking

22
Q

What is airway resistance?

A

It’s the friction versus the cross sectional area

23
Q

What does alveolar surface tension do?

A

It tries to decrease alveolar size

24
Q

What prohibits lung collapse?

A

Surfactant

25
Q

What does surfactant do?

A

It prohibits lung collapse

26
Q

What is lung compliance?

A

The stretchiness of lungs

27
Q

What does the stretchiness of the lungs include?

A

Defensibility and alveolar surface tension

28
Q

What measures the stretchiness of the lungs?

A

Lung compliance

29
Q

How does oxygen bind with red blood cells?

A

Oxygen binds with the heme’s iron in red blood cells

30
Q

What does oxygen bind with?

A

It binds with the heme’s iron in red blood cells

31
Q

What is the plurae?

A

The surface of the lungs and diaphragm

32
Q

How does the plurae help the lungs inflate?

A

The muscles pull on the visceral plurae, which then pulls on the fluid and on the parietal plurae.

33
Q

What does the plurae do?

A

It inflates the lungs by reestablishing a vacuum

34
Q

What is the average vital capacity?

A

4800ml

35
Q

What is the average lung capacity?

A

5,500

36
Q

What is the average tidal volume?

A

500

37
Q

What does an increased temperature do?

A

It decreases the affinity for oxygen

38
Q

What does a decreased pH do?

A

It decreases the affinity for oxygen

39
Q

What does a decreased temperature do?

A

It increases the affinity for oxygen

40
Q

What does an increased pH do?

A

It increases 02 affinity

41
Q

Is temperature directly or inversely proportional to oxygen affinity?

A

Inversely

42
Q

Is pH directly or inversely proportional to oxygen affinity?

A

Directly

43
Q

Is CO2 partial pressure directly or inversely proportional to oxygen affinity?

A

Inversely

44
Q

Is BPG directly or inversely proportional to oxygen affinity?

A

Inversely
