Why does the difference between the % of inhaled and exhaled air exist?
coz exhaled air has less O2 than inhaled air. This is coz some of the O2 inhaled is used up by body to release energy by aerobic resp.Exhaled air has more CO2 coz CO2 is produced when energy is released by aerobic resp.Body needs rid CO2=breathe out

Why is it benefitial to use mouth-to-mouth resuscitation when a person has stopped breathing?
Because inhaled air contains 20% oxygen and 0.04% CO2 and exhaled air contains 16% oxygen and 4% CO2.

What is your breathing rate?
The amount of breaths taken in, in 1 minute
8 of 20
What is tidal volume?
The amount of air inhaled and exhaled with each normal breath at rest or during exercise.

What is vital capacity?
The most air you can possibly breathe in after breathing out the largest volume of air you can

What is oxygen debt?
The amount of oxygen required after anaerobic exercise above that normally used at rest

What is anaerobic and aerobic respiration?
Anaerobic = Without oxygen Aerobic = With oxygen
12 of 20
Name a sport associated with anaerobic and aerobic respiration?
Anaerobic = 100 m or 200 m Aerobic = Jogging, tennis, hockey

Name 2 immediate effects of exercise on the respiratory system?
1. Breathing rate increases because the body needs to take in more oxygen so the muscles can produce more energy eg. if a sprinter has more energy=train/run longer. 2. Breathe deeper=your tidal volume will inc. because you're forcing lungs to expand

What are the short term effects on the respiratory system?
oxygen debt is created=youve consumed more O2 that youve been able to breathe in-->deep breathing, you breathe in more O2---> muscles produce energy, you breathe out CO2 (waste product)

What is the aerobic equation?
Glucose + Oxygen ---> Carbon dioxide + Water + Energy
16 of 20
What is the anaerobic equation?
Glucose ---> Lactic acid + Energy
17 of 20
What are the long term effects of exercise?
size of lungs increases --->VC Increases, number of aveoli increases, increased capillarisation,,,better at dealing eith oxygen debt, more efficient of removal of CO2

What is VO2 max?
The amount of oxygen you use (the %) during excersice

How can smoking affect/damage your respiratory system?
Tar and nicotine makes your lungs go black, carbon monoxide from the cigarettes attaches to the haemoglobin and restricts your blood flow, tar sticks to the cilla(little hairs allong the lungs, veins), tar narrows airways= short of breath,hrt wks hdr
