304 DISSECTION OF THE BABBIT 



1. The liver is a large dark-red body at the anterior end of 



the abdominal cavity, extending further back on the 

 left side than on the right. 



2. The stomach lies immediately behind the liver and 



is partially covered by it : its surface is smooth and 

 of a bluish white colour. 



3. The duodenum is a narrow pinkish tube, a small part of 



which is seen to the right of the stomach. 



4. The small intestine is a long, narrow, much convoluted 



tub, part of which is seen at the left side of the 

 abdominal cavity, behind the liver. 



5. The caecum is a very wide tube, of a dark colour, coiled 



on itself and marked by a spiral constriction. In the 

 natural position of the parts it covers almost all the 

 other viscera behind the stomach. Along the right 

 side the caecum ends in the pale fleshy vermiform 

 appendix, 



6. The colon is a wide tube, with markedly sacculated walls, 



running obliquely across the abdomen between the 

 folds of the caecum. 



7. The rectum is a white tube, dilated at intervals by the 



faecal pellets : small parts of it are seen to the 

 right of the stomach, and at the hinder end of the 

 abdomen. 



8. The bladder is a thin-walled sac at the posterior end of 



the abdomen, just in front of the pubic symphysis.

 anything, to expose the following parts. 



9. The spleen is an elongated dark-red body lying behind 



the stomach, and attached to its left or cardiac end. 



10. The kidneys are a pair of compact ovoid bodies attached 



to the dorsal wall of the abdomen ; the right one 

 being immediately behind the liver, and the left one 

 about an inch and a half further back. In front of 

 each kidney is a small, round, yellow adrenal body, 



11. The diaphragm is a muscular partition forming the 



anterior wall of the abdomen, and separating it from
