The air enters the lungs, the nose, and then starts the channel into the cavity which contains the nose lining area of skin and mucus, for capturing silia dirt. The air will move to the throat (pharynx), voice box (larynx), into which a voice (vocal cord) from the air, it's into the wind, it tube. The end of the pharynx splits into separate lung connectors to the left and right lung two sides that are smaller and more vulnerable branch called the windpipe opening (bronchiole) the walls of the pharynx the thinner filament respectively. The end of the lamp filament is a reasonably small bag with some walls, is called the wind bag (alveolus), pharynx and trachea windpipe opening beginning consists of cartilage to prevent out of air from the pressure of the surrounding tissue.

Air enters the lungs by getting into the nasopharynx. Then enter the nasal epithelium with a mucus for Celia and trapped them. Air moves to the throat (pharynx) into the voice box (larynx), which has a voice (vocal cord) from the air, into the trachea. End of the windpipe splits into separate terminal lung to lung left and right two sides, which are smaller and smaller branches called Bronchiolitis (bronchiole) of Bronchiolitis wall becomes thinner, respectively. The end of the capillary tube into a small bag. With thin walls called alveoli (alveolus) the trachea and the bronchial tree bronchiole part consists of cartilage. To prevent the collapse from the pressure of the surrounding tissue.

Air into the lungs by starting in the nasal passages. And then into the sinus area which has a membrane with cilia and mucilage for trap dirt. The weather will continue move the pharynx (pharynx) into the larynx (larynx) which inside. Sound.Cord), then the air is entering the trachea. The end of the trachea is separated into separate lung hilum to the left and right sides, which are both 2 branching smaller passive called bronchiolitis (bronchiole). The walls of the bronchioles are thin, respectively.With thin walls called alveoli (alveolus) the air hose, trachea and bronchiole proximal consists of cartilage. To prevent the air from the pressure of the tissue around the
