On the inner surface there is a vertical notch called the hauth: Betow and in front of the hilum there is a deep concavity, called the cardiac impression, to accommodate the heart.Each lung is enclosed in a serous sac, the pleura, one layer of which is closely adherent to the walls of the chest and diaphragm the other closely covers the lung ; they move easily upon, one another and prevent the friction that would otherwise occur between the lung and the walls of the chest with every respiration.Pronunciationrespiratory - [ris'paiorot3ri] respiration - [,respo'reilm] larynx -trachea - [tro'ki:3]bronchus - ['bronkos] ; pl. bronchi - ['brookai]
