 tended digestory canal, 

 from oesophagus, 6, 7, to

 into distended stomach ;

 ture; 14, pylorus con- 

 tracted ; 15, ascending,

 20, duct from liver; 21, 

 duct in common; 22, 

 opening of 21 ; and 23, 

 duct of pancreas; 24, 

 curvature forward of du- 

 odenum ; 25, jejunum ; 

 26, ileum ; 27, ileum slit- 

 ted, and opening, at 28, 

 into colon; 29, fold-like 

 valve; 30, coecum; 31, 

 vermiform appendage ; 

 32, ascending, 33, trans- 

 verse, 34, descending, 35, 

 sigmoid, 36, rectal colon. 

 The jejunum and ileum 

 do not pass directly nor so 

 many times from side to 

 side, as shown. (Fig. 100.) 



into the duodenum, about twelve finger-breadths long, 

 as its name signifies ; the jejunum, or empty, about ten 

 feet, and the ileum about fifteen feet, long. 



1083. THE DUODENUM extends upward and back- 

 ward toward the liver, turns down, and then, deeply 

 situated (see Fig. 233), crosses to the left side, near 

 which it extends forward. 



1084. THE APPENDAGES OF THE DUODENUM are the 

 pancreas, Brunner's, Lieberkuhn's, and Peyer's glands, 

 the liver, and gall-bladder.
