The lungs are spongy and porous, and their tissues are very elastic. They're lined with a delicately constructed however strong sac, identified as the pleural sac, one wall of which closely adheres to the lung, and the opposite to the inner wall of the chest, and which secretes a fluid which permits the internal surfaces of the walls to glide simply upon one another within the act of respiratory. The Air Passages consist of the inside of the nose, pharynx, larynx, windpipe or trachea, and the bronchial tubes.
