SUMMARY
The discussion focuses on calculating the number of breaths taken by a warm-blooded vertebrate based on the volume of air inhaled daily and the conditions inside the lungs. The vertebrate inhales 250 L of air per day at standard temperature and pressure (0°C, 1 atm). The air in the lungs is at 43°C and 440 mm Hg, necessitating the use of the ideal gas law (PV = nRT) and the equation P1V1 = P2V2 to determine the effective lung volume. The solution involves converting the lung conditions to standard conditions or vice versa to find the number of breaths taken per day.
