P1 19. The short term effects of exercise on the respiratory system

Question 1

what is tidal volume

Answer 1

the amount of air inhaled per breath
measured in millimetres
depth of your breathing
around 500ml
TV

Question 2

what is frequency

Answer 2

the number of breaths taken per minute
rate of breathing
around 12 to 20 breaths
f

Question 3

what is minute ventilation

Answer 3

the amount of air inhaled and exhaled in one minute
measured in litres
VE

Question 4

what is vital capacity

Answer 4

the maximum amount of air exhaled following a maximum inhalation

Question 5

what is the minute ventilation equation

Answer 5

Tidal Volume x Frequency = Minute ventilation
TV x f = VE

Question 6

what are the short term effects of exercise on the respiratory system

Answer 6

you’re lungs and working muscles require more oxygen
you have to inhale more air
frequency of breathing and TV increase
more oxygen to diffuse into blood stream to circulate the blood stream
increase in CO2 made, needs to be exhaled
increased frequency and TV allows this to happen

Question 7

what happens when resting

Answer 7

frequency is relatively low at around 12-15 breaths per min
tidal volume is relatively low at 500ml

Question 8

what happens during exercise

Answer 8

TV increases to bring more air into lungs per breath
frequency increases as air is inhaled and exhaled quicker
