Modern texts usually divide the space of the red pulp into [[cords of Billroth]] and [[sinusoids]]. ==Cells found in red pulp== The meshes of the reticulum are filled with [[blood]]: * The ''[[white corpuscles]]'' are found to be in larger proportion than they are in ordinary blood. * Large rounded cells, termed ''[[splenic cells]]'', are also seen; these are capable of ameboid movement, and often contain pigment and red-blood corpuscles in their interior. * The ''cells of the reticulum'' each possess a round or oval nucleus, and like the splenic cells, they may contain pigment granules in their cytoplasm; they do not stain deeply with carmine, and in this respect differ from the cells of the [[Malpighian bodies]]. * In the young spleen, ''[[giant cells]]'' may also be found, each containing numerous [[cell nucleus|nuclei]] or one compound nucleus. * Nucleated ''[[red-blood corpuscles]]'' have also been found in the spleen of young animals. ==See also== * [[spleen]] * [[white pulp]] * [[marginal zone]] ==External links== * {{AnatomyAtlasesMicroscopic|09|175}} - "Spleen: Red Pulp" * {{eMedicineDictionary|red+pulp}} * [http://owensboro.kctcs.edu/gcaplan/anat2/notes/Image426.gif Diagram at kctcs.edu] * [http://www.apsu.edu/thompsonj/Anatomy%20&%20Physiology/2020/2020%20Exam%20Reviews/Exam%202/CH20%20Lymphatic%20Organs%20&%20Pathology%20Terms.htm Description and diagram at apsu.edu] {{anatomy-stub}} {{Gray's}} {{Lymphatic system}} [[Category:Hematology]]
