1
Q

Respiration

A

exchange of gases between the atmosphere, blood, and cells

2
Q

Ventilation

A

breathing.

Surface tension, elastic recoil, & compliance (ease lungs can be expanded (all affect ventilation)

3
Q

Tidal Volume (TV)

A

volume of inspired or expired air with each normal breath

4
Q

Inspiratory Reserve Volume (IRV)

A

amount of air that can be inspired forcefully after inspiration of tidal volume

5
Q

Expiratory Reserve Volume (ERV)

A

amount of air that can be inspired forcefully after inspiration of tidal volume

6
Q

Residual Volume (RV)

A

amount of air left in respiratory passages and lungs after maximal forced expiration

7
Q

Inspiratory Capacity (IC)

A

IC = TV + IRV (maximum amount of air that can be inspired after normal expiration)

8
Q

Vital Capacity (VC)

A

VC = IRV + TV + ERV (maximum volume of air that can be expelled after a maximum inspiration)

9
Q

Respiratory Minute Volume (RMV)

A

the amount of air that enters your lungs in a minute

10
Q

Atmospheric Pressure

A

760mmHg (usual) pressure in enviorment

11
Q

Inspiration (in relation to diaphragm)

A

diaphragm contracts

12
Q

Expiration (in relation to diaphragm)

A

diaphragm relaxes

13
Q

Intrapleural Pressure

A

Pressure inside lungs:
Inspiration- decreases
Expiration- increases

14
Q

Alveolar Pressure

A

Pressure in aveoli:
Inspiration- drops below atmospheric pressure
Expiration- increases above atmospheric pressure

15
Q

Pulmonary Gas Exchange

A

blood reaches alveoli for O2 and then blood travels to left atrium to ventricles -> systemic circulation

16
Q

Systemic Gas Exchange

A

blood delivers O2 to tissue cells

17
Q

Spirometer

A

Used to test for asthma or COPD.

Measures ventilaiton

18
Q

Spirogram

A

Graphic record of breathing! (read RIGHT to LEFT!!!)
