respiration during exercise

Question 1

what are the three functions of the lung

Answer 1

remove co2
replace o2
regulation of acid-base balance

Question 2

what is ventilation

Answer 2

mechanical process of moving air in and out of the lungs

Question 3

the diaphragm is the

Answer 3

only muscle in body essential for life

Question 4

during diffusion where does oxygen move

Answer 4

through the alveoli to the capillaries

Question 5

during diffusion where does carbon dioxide move

Answer 5

through the capillaries to the alveoli then is exhaled

Question 6

what is the conducting zone made up of

Answer 6

treachea
primary bronchus
bronchial tree
terminal bronchioles

Question 7

what is the purpose of the conducting zone

Answer 7

gets air into the lungs

Question 8

what is the respiratory zone made up of

Answer 8

terminal bronchiole
respiratory bronchioles
alveolar sacs
alveolus

Question 9

what is the purpose of the respiratory zone

Answer 9

movement of gases from lungs to bloodstream and movement of gases from bloodstream into lungs

Question 10

3 roles of the conducting zone

Answer 10

warms air, humidifies air, filters air

Question 11

what is bOyLe’s Law?

Answer 11

the volume of a gas is inversely proportional to the pressure

Question 12

if the volume of the gas in a closed container increases …

Answer 12

the pressure of the gas decreases

Question 13

if the volume of the gas decreases …

Answer 13

the pressure of the gas increases

Question 14

when does inspiration occur

Answer 14

when atmospheric pressure is greater than it is in the lungs

Question 15

when does expiration occur

Answer 15

when pressure is greater in your lungs than in the atmosphere

Question 16

how do you calculate tidal volume

Answer 16

minute ventilation / breathing frequency

Question 17

what does airFLOW depend on

Answer 17

-pressure difference between 2 ends of airway
-resistance of airways

Question 18

what does airway resistance depend on

Answer 18

diameter

Question 19

what is DALTON’s law

Answer 19

the total pressure of a gas mixture is equal to the sum of the pressure that each gas would exert independently

Question 20

partial pressure calculation

Answer 20

fraction of % of air X barometric pressure

Question 21

when you inhale, the partial pressure of oxygen is higher in the lungs than bloodstream, therefore you get the movement of oxygen from lungs ->

Answer 21

into the bloodstream

Question 22

the partial pressure of carbon dioxide is higher in the bloodstream, therefore you get the movement of carbon dioxide from the bloodstream ->

Answer 22

into the lungs

Question 23

what means that you get the movement of gases from the bloodstream -> tissue and from tissue -> bloodstream

Answer 23

partial pressure concentration differences

Question 24

at the tissues there is a low partial pressure of o2 therefore you want

Answer 24

the formation of deoxyghemoglobin

Question 25

at the lungs there is a high partial pressure of o2 therefore you want

Answer 25

the formation of oxyhemoglobin

Question 26

oxygen is transported to the muscle via

Answer 26

hemoglobin which shuttles o2 from cell membrane to mitochondria

Question 27

myoglobin has a higher affinity for…

Answer 27

oxygen than hemoglobiin

Question 28

whats the oxyhemoglobin equation

Answer 28

dexoyhemoglobin + o2 <- -> oxyhemoglobin

Question 29

what does the oxyhemoglobin equation direction depend on

Answer 29

-partial pressure of o2
-affinity between haemoglobin and o2

Question 30

at lungs, high PO2 =

Answer 30

formation of oxyhemoglobin

Question 31

at lungs, low PO2 =

Answer 31

release of o2 to tissues

Question 32

what 3 factors result in offloading of oxygen

Answer 32

-increase in temperature
-increase in hydrogen ions
-increase in DPG
