<P> In humans the spleen is purple in color and is in the left upper quadrant of the abdomen . </P> <P> The spleen, in healthy adult humans, is approximately 7 centimetres (2.8 in) to 14 centimetres (5.5 in) in length . It usually weighs between 150 grams (5.3 oz) and 200 grams (7.1 oz). An easy way to remember the anatomy of the spleen is the 1 × 3 × 5 × 7 × 9 × 11 rule . The spleen is 1 by 3 by 5 inches (3 by 8 by 13 cm), weighs approximately 7 oz (200 g), and lies between the 9th and 11th ribs on the left hand side . </P> <P> The spleen is underneath the left diaphragm, and has a smooth, convex surface that faces the diaphragm . It is underneath the ninth, tenth, and eleventh ribs . The other side of the spleen is divided by a ridge into two regions: an anterior gastric portion, and a posterior renal portion . The gastric surface is directed forward, upward, and toward the middle, is broad and concave, and is in contact with the posterior wall of the stomach . Below this it is in contact with the tail of the pancreas . The renal surface is directed medialward and downward . It is somewhat flattened, considerably narrower than the gastric surface, and is in relation with the upper part of the anterior surface of the left kidney and occasionally with the left adrenal gland . </P> <P> Near the middle of the spleen is a long fissure, the hilum, which is the point of attachment for the gastrosplenic ligament and the point of insertion for the splenic artery and splenic vein . There are other openings present for lymphatic vessels and nerves . </P>
