The =spleen= is bright red in color in the fresh state. It is somewhat
falciform, long, and narrow; the ventral part 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 which the vessels and
nerves are situated. The dorsal end lies against the left kidney and
left crus of the diaphragm. 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.
