Abstract
What Are Your Volumes and Capacities?
By use of a Collins respirometer, students measure their inspiratory reserve volume, expiratory reserve volume, tidal volume and determine vital capacity. Resting measurements compared with values obtained after exercise may reveal individual homeostatic mechanisms. This exercise may be extended by pooling and analyzing class data.

Appropriate Levels
Life Science, High School, Honors, or Advanced Placement Biology.

Time Required
Preparation time: 5-10 min. to set up each respirometer.
Class time: a minimum of 6 min. per student per respirometer. (This lab may run concurrently with the lung model lab.)
