350 SPECIAL ANATOMY. 



and open into the plexus lumbalis, after they have united with those of 

 the supra-renal capsules, and received those of the ureters. 

 2. Lymphatics of the urinary bladder open into plexus hypogastricus. 

 6. Organs of generation : 



1. Lymphatics of the testicle pass in the spermatic cord, and in the sper- 

 matic vessels, forming a plexus spermaticus to the flex, lumbalis. 



2. Lymph, of corpora cavernosa pass with the art. pudenda under the 

 symphysis pubis to the plex. hypogastricus, to which also those of the 

 seminal vesicles and preputial glands proceed. 



3. Lymph, of female internal organs of generation. Those of the collum 

 uteri pass to the plexus hypogastricus and plexus sacralis; the remain- 

 ing lymphatics of the uterus to the superior angles of the last, and 

 thence, united with those of the tubce, the ovaria, and ligg. lata, with 

 the vasa spermatica to plex. lumbalis. 



604. HI. The Lacteals [lymphatics] and Lymphatic Glands 

 of the organs of digestion. 



1. Small intestines. a. Lymphatic glands. 



Gland, mesentericce, 130 to 150, and situated in rows between the laminae 

 of the mesenterium, the largest at the origin, and at the extremity of 

 vasa mesaraica superiora. The former, are gl. duodenales, they lie be- 

 fore the duodenum; the latter are gl. ileo-colicas, in the angle between 

 ileum and colon. (They readily inflame.) 



b. The lymphatics are particularly numerous in the so-called Jejunum. 

 The superficial arise from the serous and muscular coats ; the deep, vasa lac- 

 tea, which, during the process of digestion carry white chyle from the villi of 

 the mucous membrane, and pass from gland to gland around the truncus cce- 

 liacus, to form the middle root of the ductus thoracicus. 



2. Of the large intestines, a. Lymphatic glands. 



Gland, mesocolicce, twenty to fifty, are placed connected with the gl. mesen- 

 tericce. They are most numerous in the mesocolon transversum, along the 

 vascular arches of art. and vv. colicce. 



b. Lymphatics. Those of the cozcum, colon ascendens, and transversum, 

 pass through gl. mesocolic. to the gl. mesenteries ; those of the colon descen- 

 dens and rectum to the gl. lumbales and sacrales. 



3. Of the stomach, a. Lymphatic glands. 



1. Gl. gastro-epiploicoe superiores (four to six) are situated in the small 

 omentum on the small curvature along the art. coronar. ventrk. sinis- 

 tra. 



2. Gl. gastro-epiploicce inferiores (six to eight) in the great omentum on the 

 great curvature, along the art. coron. ventric. dextra. They are espe- 

 cially accumulated about the ostia pyloricum and cardice, and they send 

 their vasa efferentia to the gland, cceliaca. 



b. Lymphatics. The superficial form a plexus beneath the peritoneal in- 

 vestment; the deep, likewise, upon the mucous membrane, and they incline,
