Respiratory system & energy Flashcards
Inhale?
Breathe in air
Exhale?
Breathe out air
Gaseous exchange?
oxygen from alveoli > capillaries
carbon dioxide from capillaries > alveoli
Diffusion?
molecules move from from an area of high conc to an area of low conc to balance
Cardio - respiratory system?
to continuously supply muscles with oxygen
remove carbon dioxide
Aerobic?
working at a moderate intensity
gives time for body to produce energy from oxygen
Anaerobic?
working at a high intensity
without oxygen for energy production
Lactic acid?
by-product of energy production
formed when exercising anaerobically
high intensity
build up = muscle fatigue
Intensity?
how relatively powerful something is
Energy?
the capacity to do work
Carbohydrate?
fuel for aerobic & anaerobic activity
eg: pasta & bread
Glucose?
carbohydrates converted into glucose
used as fuel in energy production
Fat?
fuel for aerobic activity
eg: butter & oil
Fatty acids?
fats converted into fatty acids
used as fuel in energy production
Aerobic energy equation?
glucose + oxygen > energy + CO2 + water
Anaerobic enbergy equation?
glucose > energy + lactic acid
Tidal volume?
TV
amount of air inhaled or exhaled per breath
Frequency?
f
Number of breaths taken per minute
normal:12-20
Minute ventilation?
VE
amount of air inhaled or exhaled per minute
Vital capacity?
Maximum amount of air exhaled after a maximum inhalation
Respiratory equation?
Tidal volume x frequency = minute ventilation
