21
Q

Each inhalation and exhalation moves about how many ml of air into and out of the lungs

A

500ml

22
Q

Tidal volume

A

The volume of one breath.

23
Q

The total volume of air inhaled and exhaled each minute is equal to breathing rate multiplied by tidal volume is called

A

minute ventilation

24
Q

Minute ventilation (MV):

A

MV = 12 breaths/min x 500 mL/breath (6000 mL/min or 6 liters/min)

25
Q

About what percent of tidal volume actually reaches the respiratory
bronchioles and alveolar sacs and thus participates in gas exchange.

A

70%

26
Q

Instrument used to measure respiratory rate and the amount of air inhaled and exhaled when breathing is called

A

spirogram

27
Q

normal pattern of quiet breathing is called

A

Eupnea

28
Q

an upward and outward movement of the chest is called

A

Costal breathing (shallow)

29
Q

outward movement of the abdomen

A

Diaphragmatic breathing (deep)

30
Q

External Respiration is

A

Pulmonary Gas Exchange

31
Q

The volume of air that remains even after expiratory reserve volume is expelled is called

A

residual volume

32
Q

The sum of inspiratory reserve volume, tidal volume, and

expiratory reserve volume

A

Vital Capacity (VC):

33
Q

what is the most common gas in atmosphere

A

Nitrogen

34
Q

what is the 2nd most common gas in atmosphere

A

Oxygen

35
Q

air move on a gradient from

A

high to lower

36
Q

internal respirations is

A

systemic gas exchange

37
Q

what % of O2 is contained in blood plasma

A

1.5%

38
Q

what % of O2 is bound to hemoglobin hgb in RBC’s.

A

98.5%

39
Q

When blood PO2 is high, hemoglobin binds

A

large amounts of O2 and is

fully saturated

40
Q

When blood PO2 is low,

A

hemoglobin releases O2.

41
Q

Besides PO2 other factors influence O2 release from hemoglobin

A

Carbon Dioxide

Acidity

Temperature

42
Q

Carbon Dioxide Transport. Transported in blood in three main forms:

A

CO2 =7%

amino acids=23%

Bicarbonate ions=70%

43
Q

The area from which nerve impulses are sent to the respiratory
muscles to control respiratory rate. Located in both the Pons and Medulla Oblongata

A

Respiratory Center

44
Q

Medullary Respiratory Center. Located in the Medulla Oblongata, controls what

A

basic rhythm of respiration

45
Q

Generates nerve impulses establishing basic rhythm of quiet normal breathing.

A

Dorsal Respiratory Group (DRG)

46
Q

Nerve impulses last for approx how many seconds

A

2 sec

47
Q

Neurons of this area supply nerve impulses for forceful exhalation and remain
inactive during quiet breathing.

A

Ventral Respiratory Group (VRG)

48
Q

Plays a role in both inhalation and exhalation by modifying the
rhythm of breathing generated by the VRG as when exercising, speaking, or sleeping

A

Pontine Respiratory Group (PRG)

49
Q

The respiratory system is very responsive to levels

A

CO2 and O2 in body

fluids.

50
Q

Central Chemoreceptors: Located in the medulla, respond to changes in what elements in the cerebrospinal fluid in the CSF.

A

H+

PCO2
