Spleen: red and white pulp
This image demonstrates areas of white pulp surrounded by red pulp. Red pulp is composed of splenic cords (cords of Billroth) separated by splenic sinuses. After passing through vessels in the white pulp, blood continues into the splenic sinuses in the red pulp. Splenic sinuses eventually anastomose to form splenic veins which travel in the trabeculae to exit the spleen. 100x
