How does a llamas breathe?

Llamas breathe through their nostrils, which are large and capable of opening widely to allow for increased airflow, especially at high altitudes. They have a specialized respiratory system that includes large lungs and a unique structure of air sacs that help them efficiently extract oxygen from the thin air. Their breathing rate can increase significantly during exertion, allowing them to adapt to various physical demands. Overall, their respiratory adaptations enable them to thrive in the mountainous environments of South America.
