WebAnimal respiratory systems are designed to facilitate gas exchange. In mammals, air is warmed and humidified in the nasal cavity. Air then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange. WebGas Exchange In Mammals. 786 Words4 Pages. Since fish live in water, which has a lower concentration of oxygen in it than air, it requires more of the fishes resting energy to be used for gas exchange, over 10%, which is higher compared to mammals and insects who take in air to get oxygen, mammals use 1-2% of resting energy for gas exchange.
