Topic 8 Key WordsAlveoli – Tiny air sacs in the lungs that allow gas exchangeResiratory system– The lungsBreathing rate– The number of breaths in 1 minuteBreathing depth– Also called tidal volume. It is the amount of air you breath in and out in 1 breath. Basically it is how deeply you breathTidal Volume– Is how deeply you breath. Defined as the amount of air breathed in and out in 1 breathVital capacity– The maximum amount of air you can inhale or exhale in the most forceful breath possibleAerobic exercise– Steady exercise. This type of exercise uses oxygen and no oxygen debt is createdAnaerobic exercise– Fast intense exercise. This type of exercise does not use oxygen and therefore builds up an oxygen debtOxygen debt – The extra oxygen needed to be repaid at the end of exercise

Topic 8 Quiz Answers1. (c) The amount of air breathed in and out in 1 breath2. (a) The number of breaths you make in 1 minute3. Increased breathing rate = Short term

Increased tidal volume = short termIncreased lung capacity = long termIncreased number of alveoli = long term

4. (b) Tidal Volume5. (a) The extra oxygen rapid to the body at the end of

exercise.6. (c)Breathing rate and depth (tidal volume) stay higher for

several minutes at the end of exercise7. (b) Waste products such as carbon dioxide are removed

from the body

Topic 8 Quiz Answers8. Increased numbers of alveoli / increased lung capacity /

increased vital capacity9. (b) At the end of each round10. Smoking damaged the alveoli
