“…Spleen was shown to produce mainly lymphoid, granular cells and thrombocytes (Soldatov, 2005;Mahabady et al, 2012;Witeska, 2013). Furthermore, the key function of spleen in higher vertebrates is elimination and degradation of aged RBCs by melanomacrophage centers (Borgioli, Frangioni, 1997;Galindez., Aggio, 1998;Kurtović et al, 2008). Spleen also contains reticular tissue that ensures organ contraction and release of RBCs into circulating blood.…”
