594 LYMPHATICS OF THE CHEST. 



jected from any of the large trunks, by the yielding of 

 the valves. The superficial set are found all over the 

 convex and concave surfaces of the liver, pursuing dif- 

 ferent directions. On the convex surface some are seen 

 to enter' the suspensory ligament and pass through the 

 diaphragm to the glands in the anterior mediastinum; 

 others go to the horizontal, thence to the transverse fissure, 

 and on to the glands of the omentum minus and pylorus ; 

 while others are seen to accompany the vena cava into the 

 chest, and enter the thoracic duct. On the concave surface 

 of the liver they are equally numerous, some passing to 

 the lesser omentum, and others to the superior lumbar and 

 inferior intercostal glands. A distinct plexus is seen 

 around the gall-bladder. 



The deep lymphatics of the liver take the course of the 

 portal vessels and biliary ducts, and pass to the glands of 

 the lesser omentum, and thence back to the spine to enter 

 the thoracic duct. The lymphatic glands of the liver are 

 found along the hepatic vessels, and continuous with those 

 on the coeliac artery. 



The Lymphatics of the Pancreas and Spleen pass to the 

 glands along the splenic artery, and finally terminate in 

 the thoracic duct. 



The lymphatics of the abdominal parietes follow the course 

 of the epigastric, ilio-lumbar, circumflexa ilii, and lumbar 

 arteries, and go to the iliac and lumbar glands. Those of 

 the diaphragm join the intercostal and internal mammary, 



THE LYMPHATICS AND GLANDS OF THE CHEST. 



The lymphatics of the chest are divided into the parietal 

 and visceral. The former pursue the course of the thoracic, 

 internal mammary, and intercostal vessels, and go to the 

 axillary, inferior cervical, and intercostal glands. 



The visceral lymphatics belong to the lungs, the heart, 

 and thymus gland. 



Those of the lungs are superficial and deep. The former 

 are spread as a net-work over the pulmonary surface be- 

 neath the pleura, and proceed to the root of the lungs to
