Question 1
Question
What is the average total lung capacity?
Answer
-
5 litres
-
4.5 litres
-
6 litres
-
4 litres
Question 2
Question
Normal breathing, also known as the [blank_start]tidal[blank_end] volume, has an average volume of [blank_start]300[blank_end]-500 cm3.
Answer
-
tidal
-
300
Question 3
Question
Both maximum inspiration and maximum expiration has an average volume of 3.5 dm3.
Answer
- True
- False
Question 4
Question
Residual air, which is not [blank_start]removed[blank_end] so to keep lungs [blank_start]inflated[blank_end], has an average volume of [blank_start]1.5[blank_end]dm3.
Answer
-
removed
-
inflated
-
1.5
Question 5
Question
A spirometer measure oxygen in hameolobin.
Answer
- True
- False
Question 6
Question
Spirometer:
If a person breathes [blank_start]in[blank_end], removes air from the box, the lid will drop causing the pen to drop. This is [blank_start]in[blank_end]halation.
When they breathe out, the lid will [blank_start]rise[blank_end] and pen rises. This is [blank_start]ex[blank_end]halation.
Over time, the chamber air content will [blank_start]fall[blank_end] as the CO2 is absorbed by [blank_start]soda[blank_end] lime and oxygen is removed. Then O2 consumption can be calculated.
The graph line will go [blank_start]down[blank_end] as oxygen decreasesin the chamber. One curved "u-shape" is one [blank_start]breath[blank_end], showing inhalation and exhalation.
People with a[blank_start]sthm[blank_end]a or COPD (chronic obstructive pulmonary disease) should not take part.

iodine
-
soda lime
-
sodium carbonate
-
cyanide
Question 8
Question
Which gas is absorbed into the blood stream from the air that you inhale?
Answer
-
carbon dioxide
-
nitrogen
-
oxygen
-
water vapour
Question 9
Question
What happens to the total volume of gas in the chamber of a spirometer as you inhale and exhale?
Answer
-
it decreases
-
it increases
-
it doesn't change
Question 10
Question
Why does the total volume of gas in the chamber of a spirometer decrease as you inhale and exhale?
Answer
-
CO2 absorbed by soda lime and o2 absorbed by person
-
CO2 and O2 absorbed by soda lime
-
CO2 absorbed by person and O2 absorbed by soda lime
-
Leaks in the gas chamber
Question 11
Question
What happens to oxygen consumption as a result of excercise? Can you explain why?
Answer
-
O2 consumption decreases as muscles respire less and require less O2.
-
O2 consumption remains the same as muscles have reserves of O2.
-
O2 comsumption increases as muscles respire more and require more O2.
-
O2 consumption increases as muscles respire less and the brain requires more O2.
