An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×10×11 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 ninth and eleventh ribs on the left-hand side and along the axis of the tenth rib.

The spleen is made of red pulp and white pulp, separated by the marginal zone; 76–79% of a normal spleen is red pulp. [4] Unlike white pulp, which mainly contains lymphocytes such as T cells, red pulp is made up of several different types of blood cells, including platelets, granulocytes, red blood cells, and plasma.

In human anatomy, the splenic artery or lienal artery, an older term, is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It is known for its tortuous path to the spleen.

The trabecular arteries are the name of the branches of the splenic artery after it passes into the trabeculae of the spleen, where it branches.When these arteries then reach the white pulp, and become covered with periarteriolar lymphoid sheaths, the name changes again to central arteries (or central arterioles).
Knowledge of basic anatomic and the variations of suspensory ligament of the spleen is essential in the case of open surgery or laparoscopic splenectomy. [4] Moreover, during some surgical procedures, in many cases it is necessary to exert a certain degree of traction on the spleen and on its peritoneal insertions. This traction may result in a ...
