Paper 1
Revise: Short-term effects of exerciseRespiratory rate is the number of breaths taken per minute. Tidal volume is the amount of air moved in or out with each breath. During exercise, both increase: the performer breathes faster and takes deeper breaths.
Keep heart rate separate from stroke volume, and respiratory rate separate from tidal volume. Rate describes frequency; volume describes an amount.
