Lungs are the specialised gas exchange surfaces in mammals. Harbor seals (Phoca vitulina) are semi-aquatic marine mammals that undergo periods of prolonged apnea (breath-holding) while diving, requiring rapid and efficient ventilation upon returning to the surface.
During recovery on land, a harbor seal's respiratory parameters were monitored. Its breathing rate was recorded as 16 breaths min−116\text{ breaths min}^{-1}16 breaths min−1 and its average tidal volume was measured to be 4250 cm3.
Calculate the ventilation rate of this harbor seal in dm3 min−1\text{dm}^3\text{ min}^{-1}dm3 min−1.
