20
Q

what are cilia?

A

they are hair lace structures

21
Q

what direction is cilia moving?

A

upwards

22
Q

what do blood vessels do?

A

it warms air as it passes

23
Q

what does the decrease in volume create?

A

positive pressure

24
Q

does the fluild go in or out when there is decrease in volume?

A

the fluid goes out

25
Q

what does the increase in volume create?

A

negative pressure

26
Q

does the fluid go in or out when there is increase in volume?

A

the fluid goes in

27
Q

when the rib cage moves, what does it change?

A

it changes the volume of the chest thoracic cavity

28
Q

what makes the rib cage move up and down?

A

inter costal muscles

29
Q

what are inter costal muscles?

A

muscles between rib cage

30
Q

what happens when the diaphragm contracts?

A

increase in volume but negative pressure

31
Q

what happens when the diaphragm relaxes?

A

decrease in volume but positive pressure

32
Q

what does inhalation need?

A

energy

33
Q

inhalation is always…..

A

active

34
Q

what happens in inhalation?

A

air goes in (increase volume to create negative pressure)

35
Q

what is opposite of intercostal?

A

external

36
Q

what does intercostal muscles do in inhalation?

A

muscles cotract movinf rib cage UP then OUT so air goes in

37
Q

For inhalation, what does the diaphragm do?

A

it contracts moving diapragm down

38
Q

when diapragm contracts, what happens?

A

air goes in

39
Q

exhalation is…..

A

normal and passive

40
Q

what happens in exhalation?

A

air goes out (decrease in volume creating positve pressure)

41
Q

what does intercostal muscles do in exhalation?

A

muscles relax and rib cage drops DOWN and IN so air goes out

42
Q

For exhalation, what does the diapragm do?

A

it relaxes moving diapragm up

43
Q

In forced exhalation, what does the intercostal muscle do?

A

muscles contract moving rib cage down and in with forced (down down v ++ p)

44
Q

what happens when air is being forced out?

A

abdominal muscles will contract pushing diaphragm up with force (down down v ++ p)
