Detailed explanation-1: -As your lungs expand, air is sucked in through your nose or mouth. The air travels down your trachea, or windpipe, and into your lungs. After passing through your bronchial tubes, the air travels to the alveoli, or air sacs.
Detailed explanation-2: -Rib Cage and Abdominal Motion During normal breathing, contraction of the major inspiratory muscle, the diaphragm, produces both rib cage expansion and a downward movement of the diaphragm.
Detailed explanation-3: -Where are the lungs found? The lungs are found in the chest on the right and left side. At the front they extend from just above the collarbone (clavicle) at the top of the chest to about the sixth rib down. At the back of the chest the lungs finish around the tenth rib.
