THE SPLEEN 



The spleen is brioht red in color in the fresh state. It is somewhat falciform, 

 long, and narrow; the ventral i)art is the widest. Its position varies in accordance 

 with the fullness of the stomach. When that organ is moderately full the long 

 axis of the spleen corresponds to the direction of the last rib. Its parietal surface

is convex and lies largely against the left flank. The visceral surface is concave in 

 its length, and is marked by a longitudinal ridge, on wdiich the vessels and nerves 

 are situated. The dorsal end lies against the left kidney and left crus of the dia- 

 phragm. The ventral end is a little further back, and reaches to the ventral wall 

 of the abdomen. It is so loosely attached by the great omentum as to be regarded 

 as an appendage of the latter.
