Therefore, the spleen can see loss of S/V and spheroidicity. Interestingly, Safeukei et al then noted a heterogeneity in removal of apparently equivalently spherocytic RBCs, leading them postulate that deformation may cause a leak of intracellular ions that causes a loss in RBC volume, restoring the S/V.

The sensing of poorly deformable red blood cells by the human spleen can be mimicked in vitro

Abstract. Retention of poorly deformable red blood cells (RBCs) by the human spleen has been recognized as a critical determinant of pathogenesis in hereditary spherocytosis, malaria, and other RBC disorders. Using an ex vivo perfusion system, we had previously shown that retention of Plasmodium falciparum-infected RBCs (Pf-RBCs)

When estimated by the dilution of 51Cr-labeled red blood cells under nearly basal conditions, immature splenectomized pigs (n = 20) had a circulating red cell volume of 17.8 +/- 1.64 (SD) ml/kg. At an assumed body-to-large vessel hematocrit (BH:LH) ratio of 0.9, plasma volume was 49.6 +/- 3.12 ml/kg

Spleen: Anatomy, location and functions | Kenhub

The spleen is a secondary lymphoid organ. This means that the spleen filters blood and presents foreign particles (antigens) to the lymphocytes it houses. In this way, the spleen stimulates the maturation and activation of lymphocytes. By filtering blood, the spleen also recycles senescent and damaged erythrocytes.
