Both birds and mammals have lungs for breathing, but birds can fly at high altitudes where oxygen Class 7
Both birds and mammals have lungs for breathing, but birds can fly at high altitudes where oxygen levels are low. How might their respiratory system be adapted to help them survive in such conditions? Class 7
Answer:
Adaptations in birds' respiratory system for high altitude flight:
- Birds have highly efficient lungs with a unique system of air sacs.
- Air flows in one direction through their lungs, ensuring a constant supply of fresh oxygen-even during exhalation.
- This adaptation allows birds to extract more oxygen from the air, which is especially important at high altitudes where oxygen levels are low.
- Their blood also has a high affinity for oxygen, helping them survive and stay active while flying at great heights.
