Question 21

Lungs are the specialised gas exchange surfaces in mammals. Domestic cats are mammals.

A chronic inflammatory disease called feline asthma can affect lung function in cats. This condition can significantly reduce a cat's tidal volume.

The lung function of a Siamese cat diagnosed with feline asthma was tested. At rest, its ventilation rate was measured to be 0.80 dm3 min−10.80\text{ dm}^3\text{ min}^{-1}0.80 dm3 min−1 and its breathing rate was 32 breaths min−132\text{ breaths min}^{-1}32 breaths min−1.

Calculate the tidal volume of the Siamese cat in cm3\text{cm}^3cm3.
