The =spleen= is long and narrow. Its long axis is nearly dorso-ventral
in direction, and is slightly curved to conform to the left part of the
greater curvature of the stomach. The dorsal end lies under the
vertebral ends of the last three ribs. The ventral end is smaller,
reaches to the ventral abdominal wall, and lies against the left lobe of
the liver. The visceral surface has a longitudinal ridge on which the
hilus is situated; this divides the surface into nearly equal gastric
and intestinal areas. The spleen is attached so loosely to the stomach
that it may be regarded as being intercalated in the great omentum. In
large subjects it may reach a length of 15 to 18 inches (ca. 38 to 45
cm.) and a width of 3 to 4 inches (ca. 8 to 10 cm.).
