The volume of air taken in by a warm-blooded vertebrate in the Andes mountains is 210 L/day at standard temperature and pressure (i.e., 0 °C and 1 atm). If the air in the lungs is at 39 °C, under a pressure of 450 mm Hg, and we assume that the vertebrate takes in an average volume of 100 cm3 per breath at the temperature and pressure of its lungs, how many breaths does this vertebrate take per day?
