write me a paragraph comparing and contrasting the human respiratory system and the bird respiratory system (make it like a 7th grader wrote it)

Answer 1

The human respiratory system and the bird respiratory system are quite different, even though they both help us get the oxygen we need to live. In humans, we inhale air through our nose or mouth, which then moves down the trachea into our lungs. Our lungs have a lot of tiny air sacs called alveoli where the oxygen is exchanged for carbon dioxide. On the other hand, birds have a unique system that includes air sacs and lungs. When birds breathe in, the air goes into their air sacs first, and then it moves into their lungs where oxygen is absorbed. This means that birds can get fresh oxygen even when they exhale because of their special system. So, while both systems help us breathe, birds have a more efficient way of getting oxygen from the air, which helps them fly and stay active!
