How can yaks survive in low oxygen levels?

Yaks are specially adapted to thrive in high-altitude environments where oxygen levels are low. They possess larger lung capacities and more efficient hemoglobin in their blood, allowing for better oxygen absorption and transport. Additionally, their bodies can utilize oxygen more efficiently, enabling them to maintain energy levels despite the thin air. These adaptations are crucial for their survival in the harsh conditions of the Himalayas and Tibetan Plateau.
