interior surface terminating as dorsi-spinal, etc. Longitudi* 

 na'lss spina'ies posteridres, whole length vertebral foramen, 

 posterior surface, terminating in dorsi-spinal. V. ba'sis ver- 

 tebra'rum, from bodies of vertebrae, terminating in anterior 

 longitudinal. Medul'li-spina'les, cover cord, between pia 

 and arachnoid, from sacrum to occiput ; anas, freely with 

 those contiguous. No valves in any of the spinal veins. 



Hi'aca zter'na,inter'naand commu'nis, see lower extremity. ^ 



Ve'na ca'va iufs'rior: junction of the 2 common iliacs, up on 

 right side of aorta, terminating in lower and back part of 

 right auricle. It receives : the lumbar branches (3 or 4 in No.) 

 from muscles and integument of loins ; the right spermatic 

 (the left emptying into left renal), both having valves ; ova- 

 rian, have same termination; the renal, the left being the 

 longer; the right supra-renal (the left terminating in the left 

 renal, or phrenic); the right fhrenics (the left superior 

 emptying into superior intercostal or internal mammary, and 

 the inferior into the left renal); the hepatic, 3 branches (no 

 valves), these commencing as the iw^ra-lobular veins (in the 

 centre of the lobule), forming the .y<Mobular, and these last 

 finally the larger hepatic trunks. 



Ve'aa por'ta : 4 inches long ; no valves in it or i*s branches ; 

 formed by mesenter'ica inferior, (draining rectum, sigmoid 

 flexure, and descending colon ; its branches inosc. with in- 

 ternal iliac); ntesenter'ica supe'rior (draining small intestines, 

 caecum, ascending and transverse colon); splen'icce (5 or 6 

 branches from spleen ; receiving branches of va'sa bre'via, 

 left gas'tro-epiplo'ica, pancreat'ica and pancreat'ico-duodena'- 

 lis veins) ; gas'trica, from lesser stomachic curvature. 



Cardi'aCffl: ve'na cor'dis mag'na, from apex, up anterior 

 interventricular groove to base ventricles, curving to left side 

 to back part of heart, emptying into coronary sinus, guarded 

 by 2 valves; receives posterior cardiac and left cardiac veins. 

 Ve'na cor'dis me'dia, (posterior cardiac) from apex up poste- 

 rior interventricular groove, terminating in coronary sjnus, 

 guarded by valve. Ve'na par'vce, (anterior veins), 3 or 4 

 small branches from anterior surface of right ventricle, empty- 

 ing into lower part right auricle. Ve'na thebefsii drains mus- 

 cular substance, opening into right auricle. 



Pulmona'les : 4 in No.; commence in capillary network upon 

 bronchial cells, uniting to form a trunk for each lobe, the one 

 of the middle lobe of the right lung unites with the one from 

 the superior lobe, hence a veins from each side. No valves; 

 carry arterial blood;
