Exercise Phys

Front 1

Tidal Volume

Back 1

500ml = normal breathing

Front 2

Expiratory Reserve Volume

Back 2

Forcefully blowing out all of the air in the lungs

Front 3

Inspiratory Reserve Volume

Back 3

Forcefully breathing in as much as you can

Front 4

Vital Capacity

Back 4

Forcefully Inhaling then exhaling back to back

Front 5

Functional Residue Capacity

Back 5

amount of air left in after normal tidal volume

Front 6

Average Tidal

Back 6

500ml

Front 7

When can you get expiratory reserve?

Back 7

After normal respiration

Front 8

In-expiratory reserve volumes

Back 8

decrease with increased tidal volume

Front 9

Pulmonary ventilation

Back 9

response in ventilation to exercise

referring to the total exchange of air between the lungs and the ambient air.

Front 10

Ventilatory threshold

Back 10

where pulmonary ventilation rises exponentially

Front 11

difference bw mixed venous blood and venous blood draining the active muscle

Back 11

Mixed venous-= whole body o2 consumption

Venous blood draining active muscle-= Measure consumption of specific muscle or tissue

Front 12

Venous blood draining active muscle-=

Back 12

Measure consumption of specific muscle or tissue

Front 13

Mixed venous-=

Back 13

whole body o2 consumption

Front 14

Arterial ph

Back 14

acidity of arterial blood,,, as hydrogen goes up , ph goes down

Front 15

Anticipatory response-

Back 15

body's response to knowledge that exercise is about to begin.
Indicates a higher brain control over respiration (no need for physical stimuli)

Front 16

Carotid bodies

Back 16

detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of oxygen, but also of carbon dioxide. Furthermore, it is also sensitive to changes in pH and temperature.

Front 17

Aortic body

Back 17

measures changes in blood pressure and the composition of arterial blood flowing past it, including the partial pressures of oxygen and carbon dioxide and pH.[2] The chemoreceptors responsible for sensing changes in blood gases are called glomus cells.

Front 18

Arterial co2 ????? with exercise

Back 18

Decreases

Front 19

Motor Cortex Stimulates

Back 19

Expiratory Center, Inspiratory Center, Pneumotaxic, Apneustic

Front 20

Expiratory Center

Back 20

Rhythmically controlled by motor cortex ** Inhibits inspiratory system

Front 21

Inspiratory system

Back 21

Inhibits expiratory
& feeds INTO the lungs causing expansion

Front 22

Pneumotaxic

Back 22

facilitates the expiratory system
*** Fine tunes breathing so that it is controlled and rhymical
***if eliminated you would exhale much longer than needed

Front 23

Apneustic

Back 23

facilitates inspiratory
*also for fine tuning
***if eliminated you would inhale much longer than needed

Front 24

Afferent Factors

Back 24

Long muscle stretch receptors feed back to in-expiratory center
lung stretch receptors do the same
carotid body & aortic body (sense stretching)

Front 25

Central Theory

Back 25

High Brain
-mechano receptors
-humoral inputs in the brain
(ex. if CSF increases in CO2 concentration then Hydrogen goes UP)

Front 26

Peripheral Theory

Back 26

All comes from Peripheral system
- mechano receptors
-alterations in PH, O2, CO2 are also sensed by CHEMOreceptors

Front 27

Combined theory

Back 27

Peripheral, Humoral, and Neruoal input

Front 28

Each molecule of hemoglobin can transport ____ O2 molecules

Back 28

Four

Front 29

O2 is transported in the blood binded with _____

Back 29

Hemoglobin

Front 30

Each molecule of hemoglobin can transport ____ O2 molecules

Back 30

Four

Front 31

O2 is transported in the blood binded with _____

Back 31

Hemoglobin
