from before. Natural size. (The thymus gland pushed somewhat 

 upwards; the lungs turned aside.) 



The lungs, Pulmones, are placed one in each of the lateral cavities of the 

 chest; the concave base rests upon the diaphragm, the concave inner surface is in 

 part adapted to the convex pericardium, and the external surface, which is convex, 

 corresponds to the form of the cavity of the chest. The right lung is broader 

 and shorter than the left, and divided into three lobes, Lobi pulmonum; the 

 left is smaller, narrower and longer than the right, and has only two lobes. 

 The base is of semilunar form, the anterior border thin and sharp, the 

 posterior border rounded and broad. At the inner surface is a fissure, the 

 Hilus s. Porta pulmonis ; here the bronchus and pulmonary artery enter the lung, 

 and the two pulmonary veins have their exit from the lung. These structures, 

 the bronchus, pulmonary artery and pulmonary veins, form together the root 

 of the lung, Radix s. Pedunculus pulmonis.
