How do we get oxygen?

Answer 1

Answer:

We get oxygen by breathing in fresh air, and we remove carbon dioxide from the body by breathing out stale air. But how does the breathing mechanism work? Air flows in via our mouth or nose. The air then follows the windpipe, which splits first into two bronchi: one for each lung.
