1. The Pancreas is the long, pinkish body lying 

 in the curve of the duodenum. The pancreas has 

 two ducts opening into the intestine ; one in con- 

 nection with the bile-duct, the other about an inch 

 farther back. 



2. The Liver is the large, lobulated, red body 

 lying immediately behind the diaphragm. It is 

 suspended from the diaphragm by a fold of the 

 peritoneum, \h& falciform ligament, which divides 

 the liver into a right and left portion. These are 

 usually subdivided into the following lobes, but 

 are subject to variation : 



a. The right central lobe lies against the right 

 side of the diaphragm. It encloses the gall- 

 bladder. 



b. The right lateral lobe lies posterior to the 

 right central lobe. 



c. The caudate lobe lies on the posterior side of 

 the right lateral lobe and extends backward to 

 the kidney.
