- Homework- Gas Exchange
After watching the video clip (under lung structure post) on gas exchange in the lungs, write a detailed account of how gas exchange occurs. You need to include terms such as: surface area, diffusion, alveoli, capillary network etc You should of course...
- Lung Capacity
We will try and detrmine our lung capacities with a spirometer and by using an inverted plastic bottle full of water. Have a look at the following link to see the terms used for lung capacity: Determining lung capacity...
- #50 The Gas Exchange System
All organisms take in gases from their environment and release gases to the environment. Animals take in O2 for aerobic respiration and release CO2. Plants also respire, but during daylight hours they photosynthesise at a greater rate than...

Homework- Lung Capacity
Please finish collecting all the data on the sheet and complete all the calculations.
The following definitions (Wikipedia) may help:
Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume.
Expiratory reserve volume: the maximal volume of air that can be exhaled from the end-expiratory position
Tidal volume is the lung volume representing the normal volume of air displaced between normal inspiration and expiration when extra effort is not applied. In a healthy, young adult, TV is approximately 500 ml per inspiration or 7ml/kg body weight
Does your tidal volume fit this data? Can you think of reasons why the data may not be accurate?
What could cause your vital capacity to decrease?
Can your vital capacity be increased?
