Detailed explanation-1: -From the windpipe, air moves into the lungs through tubes called bronchi. The bronchi lead to smaller tubes called bronchioles, which look like the branches of a tree.
Detailed explanation-2: -The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.
Detailed explanation-3: -The walls of the alveoli share a membrane with the capillaries. That’s how close they are. This lets oxygen and carbon dioxide diffuse, or move freely, between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart.
