The |spleen| is an oblong, flattened, dark purple organ located between the |stomach| and the |diaphragm|. It features an ~anterior~ (frontal) extremity, a ~posterior~ (rear) extremity, and an inferior (lower) and superior (upper) margin. Its external surface is smooth and rounded, with the body generally directed upward and backward. The front portion of the lower surface rests against the |stomach| and left |kidney| and features impressions for these organs. Also in this lower surface is a fissure, called the |hilus|, which admits vessels and ~nerves~.
