How do lungs help animals adapt to the taiga?

Lungs enable animals in the taiga to efficiently extract oxygen from the cold, dense air, which is crucial for survival in this harsh environment. The respiratory systems of these animals are often adapted to cope with lower oxygen levels and extreme temperatures, allowing them to maintain energy levels during long winters. Additionally, lungs help facilitate thermoregulation, enabling animals to manage their body heat while foraging or moving in the frigid climate. Overall, efficient pulmonary function is key to thriving in the taiga's challenging conditions.
