Answer 2

When we breathe the air enters our body through our nose. Then our chest cavity increases which increase the space present in our lungs, as the lungs expand air is sucked through our nose or mouth, it travels through our windpipe then into our lungs. Then, as the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of the lungs and windpipe, and then out of your nose or mouth.
