Which organ contains red pulp and white pulp?

The spleen is specialized to have two distinct areas that reflect its blood-filtering and immune roles. White pulp is lymphoid tissue organized around central arteries and rich in T and B lymphocytes, ready to mount immune responses to pathogens in the blood. Red pulp is involved in filtering the blood itself: it contains cords and sinusoids with macrophages that remove old or damaged red blood cells and recycle iron, and it also serves as a reservoir for platelets. The other organs don’t have both regions: the thymus is focused on T cell maturation with cortex and medulla; lymph nodes filter lymph rather than blood and have their own cortical and medullary regions; the liver processes blood and bile but doesn’t present a defined red and white pulp. So, the organ with red pulp and white pulp is the spleen.
