Answer:

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.

What are the adaptations for gas exchange in mammals?

The large number and small size of the alveoli give the lungs a large surface area to volume ratio. This allows mammals to grow to much larger sizes without the limitations normally imposed by the associated increase in the size and weight of the gas exchange system.
