1

Tidal Volume

normal breathing air in = out
~500 mL

2

Inspiratory Reserve Volume

additional that can be inspired forcibly
1900-3300 mL

3

Expiratory Reserve Volume

additional expired forcibly after normal tidal expiration
700-1000 mL

4

Residual Volume

amount left in lungs after maximal expiration
1100-1200 ML

5

Inspiratory Capcity

total that can be inspired afyter normal exhalation
V + IRV

6

Functional Residual Capacity

air remaining in lungs after normal exhalation
RV + ERV

7

Vital Capacity

total amount that can be inhaled and exhaled forcibly
V + IRV + ERV

8

Total Lung Capacity

total amount air in lungs
V + IRV + ERV + RV

9

Dead Space V D

Conduction airways dont exchange gasses

10

Alveolar ventilation formula

V a = f (V t - V d)
f= breaths per min
V t = tidal volume
V d= dead space

11

Dalton's Law

total pressure exerted by a mixuture of gases is = to sum of partial pressure of each gas

12

Partial pressure calculation

% of total gas * total pressure

13

Henry Law

gases dissolve in liquid in proportion to its partial pressure,
-movement determined by differences btw partial pressure in liquid and partial pressure in air
-amount dissovled gas depends upon solubility CO2>O2>N2

14

Gases dissolved in liquid

partial pressure

15

Substantial partial pressure difference

greater to difference faster the diffusion

16

Distance to diffuse

respiratory membrance- smaller distance for faster the diffusion

17

Lipid soluble gases

go through cell membrane

18

Blood & air Flow

coordinated, higher pulmonary O2 during increased blood flow

19

Low ventilation

redirection of blood to better ventialted area

20

Vessel diameter

pulmonary O2 affects diameter length

21

High CO2 concentration

blood-bronchiole dilate and

22

CO 2 content

affects size of bronchiole diameter

23

Bronchiole

branch out from the bronchi and carry oxygen to the alveoli

24

Internal respiration

exchange of O2/CO at tissue level
via cellular respiration

25

Quiet Breathing

-Contraction of both diagram and external intercostal muscles
-Involves muscular contraction but exhalation is passive

26

Cellular respiration

involve internal respiration
-cellss metabolic requirement and exchange of waste product

27

External Respiration

exchange of O2 and CO btw intestinal fluids and external environment

28

Pulmonary ventilation def

physical movement of air in and out of lungs
