Lesson 2 Terms - Anatomy and Physiology of Respiration

Question 1

respiration

Answer 1

Exchange of gas between an organism and its environment.

Question 2

inspiration

Answer 2

The process of bringing air into the lungs for respiration.

Question 3

expiration

Answer 3

The process of eliminating air rom the lungs for respiration.

Question 4

Boyle’s law

Answer 4

Given gass of constant temperature, increasing (or decreasing) the volume of the chamber in which the gas in contained will cause a corresponding decrease (or increase) in pressure.

Question 5

bifurcates

Answer 5

Divides into two parts.

Question 6

alveoli

Answer 6

Air sacs in the lungs.

Question 7

mediastinal

Answer 7

Referring to the mediastinum or middle space of the thorax, which contains the heart.

Question 8

pericardium

Answer 8

The membranous sac enclosing the heart.

Question 9

palpation

Answer 9

Feeling a structure using one’s hands.

Question 10

parasternal

Answer 10

Near the sternum.

Question 11

spirometer

Answer 11

Devide that measures volume of air expelled of inspired.

Question 12

manometer

Answer 12

Device that measures pressure.

Question 13

breaths per minute (BPM)

Answer 13

the number of complete inhalations in exhalations performed in 1 minute.

Question 14

volume

Answer 14

In repiration, the displacement of air that represents specifically partioned components of the respiratory system, measured in cubic centimeters or cubic inches.

Question 15

capacity

Answer 15

Functional unit that is a combination of respiratory volumes, used to express physiological limits.

Question 16

milileter (mL)

Answer 16

One thosoundth of a liter.

Question 17

cubic centimeter (cc)

Answer 17

A milliliter or one thousandth of a liter.

Question 18

tidal volume (TV)

Answer 18

The volume of air exchanged during one cycle or respiration.

Question 19

Quiet tidal volume

Answer 19

Tidal volume at rest.

Question 20

inspiratory reserve volume (IRV)

Answer 20

The volume of air that can be inhaled after a tidal inspirations (approximately 2475 cc for adults)

Question 21

expiratory reserve volume (ERV)

Answer 21

The volume of air that can be expired following passive, tidal expirations (approximately 1000 cc for adults)

Question 22

residual volume (RV)

Answer 22

The volume of air in the lungs after a maximum exhalation (approximately 1100 cc in adults)

Question 23

dead air space

Answer 23

The space, representing the conductive passageway of the respiratory system, that contains a volume of air that need undergoes gas exchange (approximately 150 cc in adults)

Question 24

vital capacity (VC)

Answer 24

The combination of inspiratory reserve volume, and tidal volume, representing the capacity of air available for speech (approximately 4000 cc in adults.)

Question 25

functional residual capacity (FRC)

Answer 25

The volume of air in the thorax after a passive exhalation (approximately 2100 cc in adults)

Question 26

total lung capacity (TLC)

Answer 26

The total volume of the respiratory system that can undergo gas exchange, equaling the sum of tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume (approximately 5100 cc in adults)

Question 27

inspiration capacity (IC)

Answer 27

The maximum inspiratory volume possible after tidal expiration (approximately 3000 cc in adults).

Question 28

atmospheric pressure (Patm)

Answer 28

Pressure generated as a result of the weight of atmospheric gases.

Question 29

intramural (mouth) pressure (Pm)

Answer 29

Pressure in the oral cavity.

Question 30

subglottal pressure (Ps)

Answer 30

Pressure beneath the level of the vocal folds.

Question 31

alveolar, or pulmonary, pressure (Pal)

Answer 31

Pressure in the alveolus.

Question 32

intrapleural pressure

Answer 32

Pressure between the visceral and parietal pleurae.

Question 33

supraglottal

Answer 33

The region above the vocal folds.

Question 34

checking action

Answer 34

Using the muscles of inspiration to impede the outflow of air during expiration.

Question 35

electromyography

Answer 35

The process of measuring and recording the electrical activity associated with muscular contraction.
