    The trachea runs in the centre of the neck and goes or passes into the larynx which opens below the mouth and constitutes inspiration and expiration by means of expansion of the chest. rIhe lungs are covered on their upper surface by the pulmonary mucous membrane, a fine skin, the inner wall of the cavity of the chest, but is covered by the chest skin or pleura. Respiration is the unbroken activity of the lungs which conducts to the body the air necessary for life. It brings the oxygen of fresh air into contact with the blood as it passes through the lungs. Inspiration occurs by the drawing in of air into the trachea and its branches which causes the air cells to expand like air bubbles. In expiration the used up air is ejected from the little air cells and the expanded lungs again contract. The inspiration and expiration can be seen outwardly by the move- ment of the chest in its expansion and elevation, in its depression and contraction. The air taken into the lungs contains plen- ty of fresh oxygen while that discharged contains much less (as 16 to 21) and is foul with carbonic acid, nitrogen, and vapor. This is plainly to be seen in cold weather when in breathing out, the moisture thickens into vapour. It is clear also that where many people are con- gregated the air is perceptibly corrupted. 9* The lung tree, 1) Larynx, 2) Trachea, 3) and 4) Ramifications of the Trachea.
