Question 26

The lungs of mammals are highly adapted for efficient gas exchange. In a physiological study investigating the effects of heat stress on the respiratory dynamics of the European rabbit (Oryctolagus cuniculus), a rabbit was exposed to an elevated ambient temperature of 35 ∘C35\text{ }^\circ\text{C}35 ∘C.

Under these conditions, the rabbit's ventilation rate was recorded as 1.56 dm3 min-1 and its breathing rate was measured at 120 breaths min−1120\text{ breaths min}^{-1}120 breaths min−1.

Calculate the tidal volume of this rabbit under heat stress. Give your answer in cm3\text{cm}^3cm3.
