Dolly and Nora Test Their Lung Capacity (MP4 - 720p)
Dolly and Nora test their lung capacity (volume) prior to starting the day at the laboratory. They calibrate the spriometer to verify that it reads 3 liters of air when a calibrated syringe delivers that amount, and then take turns demonstrating that their lung capacities are remarkably close to that of the syringe.
