Q

This is referred to as fast breathing.

42
Q

44
Q

This is known as being short of breath when you lie down.

Q

This is known as lacking air.

46
Q

This is known as the amount of air that can be inhaled and exhaled during normal, quiet breathing. The average adult amount is 500ml.

A

Tidal volume (TV)

47
Q

This is known as the amount of air that can be forcibly inhaled beyond a TV. The average for women is 2,000ml and men is 3,000ml.

A

Inspiratory reserve volume (IRV)

48
Q

This is known as the amount of air that can be forcibly exhaled beyond a Tidal Volume.

A

Expiratory reserve volume (EPV)

49
Q

This is known as the amount of air that remains in the lungs after maximal expiration.

A

Residual volume (RV)

50
Q

This capacity is known as the total amount of exchangeable air. (TV+IRV+ERV)

A

Vital Capacity

51
Q

This capacity is known as the amount of air remaining in the lungs after a tidal expiration. (RV+ERV)

A

Functional residual capacity (FRC)

52
Q

This capacity is known as the total amount of air that can be inspired after a tidal expiration. (IRV+TV)

A

Inspiratory capacity (IC)

53
Q

This is known as the sum of all lung volumes (approx. 6000 ml in males).

A

Total lung capacity (TLC)

54
Q

This is known as abrupt and severe shortness of breath throughout the night, that frequently wakes a person up. It can be a sign of several underlying medical disorders, including congestive heart failure.

A

Paroxysmal Noctural Dyspnea

55
Q

This type of respiratory center is known as primary and is located in the medulla oblongata of the brainstem. They detect changes in the arterial partial pressure of carbon dioxide (pCO2). When changes are detected, the receptors send impulses to the respiratory centers in the brainstem that initiate changes in ventilation to restore normal pCO2.

A

Central Chemoreceptors

56
Q

This type of respiratory center is located in both the carotid body and the aortic body. When low levels of oxygen are detected, afferent impulses travel via the glossopharyngeal and vagus nerves to the medulla oblongata and the pons in the brainstem. A number of responses are then coordinated which aim to restore pO2.

A

Perpheral Chemoreceptors

57
Q

This part of the brain causes our involuntary breathing.

A

The Medulla

57
Q

This part of the brain fine tunes our breathing.

58
Q

This part of the brain controls our voluntary breathing, ability to sing and hold a note, and to scream.

59
Q

Because of these, anxiety and fear get a response from the hypothalamus and causes us to breathe faster.

60
Q

This is a type of mechanoreceptor that are responsible for dissention of various organs and muscles and are neurologically linked to the medulla in the brain stem via afferent nerve fibers. Examples: causes sneezing or coughing and can even stop us from breathing.

A

Stretch Receptors

61
Q

The two respiratory groups in the medulla are called:

A

The Dorsal Respiratory Group and the Ventral Respiratory Group.

61
Q

These types of receptors are sense organs or cells that respond to mechanical stimuli such as touch or sound.

A

Mechanoreceptors

62
Q

This respiratory group is made up of two areas – the pneumotaxic center and the apneustic center.

A

Pontine Respiratory Group (located in the Pons)

63
Q

This respiratory group controls our diaphragm and has the most fundamental role in the control of respiration, initiating inspiration (inhalation).

64
Q

This respiratory group has neurons that are active in forceful breathing and inactive during quiet, restful respirations.

65
Q

This type of center controls both the rate and the pattern of breathing. It’s also considered an antagonist to the center.

A

Pheumotaxic

66
Q

This type of center produces abnormal breathing during inhalation. If you hear this type of breathing, death is imminent.

67
Q

This is known as a lack of breathing for 10-20 seconds when sleeping. Most of the time it’s cause is from a person’s tongue following back and blocking their airway. IT causes fatigue, headache, drowsiness, and depression.

A

Sleep Apnea

68
Q

This is known as the amount of gas in fluid.

A

Partial Pressure

69
Q

True or False: as hydrogen ions and CO2 increase, it makes pH go down to be more acidic.

A

True, you’re breathe deeper (depth) and faster (rate).

70
Q

True or False: as hydrogen ions and CO2 decrease, it makes pH increase to become more basic.

71
Q

True or False: Aortic and Carotid Bodies are backups and respond mostly to O2.

A

True, if O2 levels are less than 50% of what they should be, they kick in.

72
Q

This reflex keeps the lungs from overinflating with air.

A

The Hering-Breuer reflex

73
Q

True or False: when performing intense workouts, the creation of lactic acid surpasses utilization, and the acid enters your blood.

74
Q

What are arteriole supplies blood to the glomerulus?

A

Afferent Arteriole

75
Q

Alcohol and coffee are examples of drinks that include chemicals that increase urine production in the kidneys. These types of chemicals are called:

76
Q

Increased blood pressure would lead to the following:

A

Increased urine production

77
Q

Water leaves the nephron by this mechanism:

78
Q

What part of the nephron is connected to the glomerulus?

A

The proximal tubule

79
Q

Promotes increased production of urine.

80
Q
