What is the respiratory system of the red fox?

The respiratory system of the red fox, like that of other mammals, consists of the nasal passages, trachea, bronchi, and lungs. Air is inhaled through the nasal passages, where it is warmed and filtered before passing through the trachea and branching into the bronchi, which lead to the lungs. In the lungs, oxygen is exchanged for carbon dioxide in the alveoli, and the oxygenated blood is then circulated throughout the body. The red fox's respiratory system is adapted for efficient gas exchange, supporting its active lifestyle as a hunter.
