APPENDIX VERMIFORMIS IN RABBIT AND 



IN MAN 



The diagram to the left shows part of the intestine 

 of the rabbit. S. I indicates the small intestine coming 

 from the stomach. Its lower end is expanded into a 

 roundish sac, the sacculus rotundus. Here is given off 

 the large blind gut or caecum, a cul-de-sac, which ends 

 in the finger-shaped vermiform appendix (App.). The 

 caecum is full of partly digested food which is thus de- 

 layed on its downward passage, before passing into the 

 large intestine (L. I). 



The diagram to the right, not drawn to scale, shows 

 similar parts in man: — S. I the lower end of the small 

 intestine; L. I the beginning of the large intestine; 

 App. the vermiform appendix, reduced to a vestige. 

 The part corresponding to the large blind gut of the 

 rabbit and of many other mammals is unrepresented 

 save by the vestigial appendix, which is the seat of 

 inflammation in appendicitis.
