Could someone help me with the definitions and explanations for these terms?

Question

Science assignment about lung capacity...

Tidal Volume

Vital Capacity

Lung Capacity

Residual Volume

Expiratory Reserve

Don't think that I'm only using this site, because I've looked all over the internet and in our encyclopedias and I keep getting the same answers for each one. To get a better mark on this assignment we need to have at least 3 references for each one, and a paragraph explaining each.

Answer 1

Tidal volume:The amount of air breathed in or out during normal respiration. The volume of air an individual is normally breathing in and out.

Vital capacity:The amount of air that can be forced out of the lungs after a maximal inspiration. Emphasis on completeness of expiration. The maximum volume of air that can be voluntarily moved in and out of the respiratory system.

Total lung capacity:The volume of gas contained in the lung at the end of maximal inspiration. The total volume of the lung (i.e.: the volume of air in the lungs after maximum inspiration).

Residual volume:The amount of air left in the lungs after a maximal exhalation. The amount of air that is always in the lungs and can never be expired (i.e.: the amount of air that stays in the lungs after maximum expiration).

Expiratory reserve volume:The amount of additional air that can be breathed out after the end expiratory level of normal breathing. (At the end of a normal breath, the lungs contain the residual volume plus the expiratory reserve volume, or around 2.4 litres. If one then goes on and exhales as much as possible, only the residual volume of 1.2 litres remains).
