Total questions: 20
Worksheet time: 12mins
What is the name of the two main branches from the trachea (one to each lung)?
bronchi
alveoli
capillaries
bronchioles
When air is pushed OUT of the lungs from an alveolus, what is the correct order for the tubes it passes through?
bronchiole -> bronchi -> trachea -> nose
bronchi -> bronchiole -> trachea -> nose
trachea-> bronchi -> bronchiole-> nose
Which one of these is NOT a function of the alveoli?
To warm air as it is breathed in
Transfer carbon dioxide
Perform gas exchange
Transfer oxygen
What is produced in anaerobic respiration in humans?
Glucose and oxygen
Carbon dioxide and water
Lactic acid
Carbon monoxide
Why does your breathing rate increase during exercise?
My breathing rate stays the same
My lungs cannot absorb oxygen while I exercise
The concentration of oxygen I breathe in decreases so I have to breath more
My cells are performing more cell respiration, which requires more oxygen
The correct word equation for aerobic respiration is
carbon dioxide + water (+ energy) → glucose + oxygen
water + oxygen → carbon dioxide + glucose (+ energy)
glucose + oxygen → carbon dioxide + water (+ energy)
glucose + water → carbon dioxide + water (+ energy)
The correct word equation for Anaerobic respiration is
glucose → lactic acid + oxygen
glucose → lactic acid (+ energy released)
glucose + oxygen → lactic acid (+ energy released)
lactic acid → energy released

I need a calculator!
What did the anaesthetist say to the surgeon after watching him perform a perfect lung transplant operation?
Well done, nice work
That was breathtaking !
Where did you learn to do that?
Would you like some r-alveoli for lunch
