In this section, the anatomy of the spleen is examined in detail. The spleen is one of the most important organs of our body and acts as an important part of the hematopoietic system and the immune system. It also plays an important role in storing and filtering blood and producing various blood cells. Anatomically, the spleen is roughly divided into two parts: the white pulp and the red pulp. The white pulp contains cells of the immune system and represents an important site for antibody production. The red pulp is responsible for filtering blood cells and recovering the reusable components of damaged cells.
