Answer 1

Answer:

The oxygen you breathe in goes into your lungs and passes into your blood from there. It is then transported to all the cells in your body through your bloodstream. The lungs are located in the chest region, protected by the ribs in the rib cage. Their structure can be compared to that of an upside-down tree: The windpipe branches into two airways called bronchi, which lead to the lungs. Inside the lungs, the airways keep branching into narrower airways until the air sacs are reached.
