What it is and what it does

The spleen lies on the left abdominal wall, cranial and ventral, parallel to the greater curvature of the stomach, in the greater omentum. Being held only by the gastrosplenic ligament, its position varies with the filling of the stomach and with its own size; the stomach is cranial and medial to it, the left kidney dorsal, medial and caudal. Its size varies greatly between breeds.

Worth remembering

Its size varies greatly between breeds.
