The Letter to the Editor by Beltrami (2021) raises questions regarding our recent work that investigated blood flow to the respiratory musculature during exercise and voluntary hyperpnoea (Ramsook et al., 2020). The comments and title of the letter are framed as ‘physiology versus statistics’. We do not view physiology and statistics as competing entities. Rather, our paper uses the time-tested method of presenting raw traces of physiological measures to illustrate the methods used along with the contemporary approach of showing data for individual subjects, mean data, and box-and-whisker plots. Our response will: (i) clarify how we see the physiological complexities of blood flow distribution to the muscles of breathing; and (ii) address selected statistical comments raised.
