. The comparative anatomy of the domesticated animals. Veterinary anatomy. 546 RESPIRATORY APPARATUS IN MAMMALIA. The external or costal face is convex (and smooth), and moulded to the external wall of the thorax. The internal, or mediastinal face, forms a vertical plane, separated from the opposite lung by the mediastinum. It shows : 1. A small anterior portion in contact with the anterior mediastinum. 2. At the heart, an excavation in which that organ is lodged. 3. Immediately behind this excavation, and a little above it, the root of the lung {hilum-pulmonis)—a fasciculus formed by the air-tubes and pulmonary vessels in entering the viscus. 4. A posterior portion, more extensive than the other two put together corresponding to the posterior mediastinum,. LUNG OF THE HORSE, SUSPENDED BY THE TRACHEA (VIEWED BY ITS BASE AND INFERIOR BORDER). T, Trachea; L, L', anterior lobes; E, E', cavity for the heart; Ap, Ap, branches of the pulmonary artery at their entrance to the heart; Vp, Vp, pulmonary veins at their emergence from the lung ; F, F, external face of the lobes of the lung ; D, D, base of the lung, or diaphragmatic face of the two lobes; H, internal lobule of the right lobe ; I, channel for the posterior vena cava; 0, oesophagus passing between the two lobes (a certain retraction of the organ appears to make it pass between the lobe and lobule of the right lung). and attached to that septum by means of a fold developed around the organ, to form the pulmonary pleura ; this fold constitutes, posteriorly, a small serous ligament {ligamentum latum pulmojiis), attached at once to the mediastinum and the posterior face of the diaphragm. On this portion of the lung are remarked two antero-posterior furrows : one, near the upper border of the organ, to receive the thoracic aorta ; the other situated lower, but not so deep, more marked in the left than the right, and lodging the oesophagus. In the right. Please note that these images are extracted from scanned page im
