LYMPHATICS AND NERVES OF THE STOMACH. 



The Lymphatics are numerous, and begin close under the epithelium by 

 dilated extremities or loops (Fig. 136, d); they run vertically, and anastomose in the 

 mucosa between the gland-tubes, which they envelope in sinus-like spaces. They 

 join large trunks in the mucosa ; another plexus of large vessels exists in the sub- 

 mucosa (Loven).

exist in the muscular coat (Auerbach's), and another (Meissner's) in the sub- 

 mucosa.] 



The Blood-vessels are very numerous. Small arterial branches, a, run in the 

 sub-mucosa and ascend between the glands to form a longitudinal capillary net-work, 

 c c, which forms a narrow net-work under the epithelium, and between its meshes 

 the gland- ducts open (g). The veins gradually collect from this horizontal 

 capillary net-work and run towards the large veins of the sub-mucosa, v.
