The present study was carried out to elucidation the main anatomical differences between the spleen of rabbit and guinea pig.Conducted on 30 animals.(15 for each type) divided into two parts. The first part (10 animals) cared for determined shape, position and ligaments of spleen as well as estimated the length, width, thickness, size, weight and relative weight of spleen in each animal. The second part (5 animals) was specified to investigate the arterial blood of spleen. The results appeared that the spleen of rabbit was tongue in shape situated in left abdominal cavity while it was quadrilateral in guinea pig located in left hypochondrial subregion. The present findings revealed that the length, width, thickness, size, weight and ratio of spleen to total body weight in rabbit was 3.314±0.16 cm,0.544±0.04 cm,0.128±0.07cm,0.488±0.03 cubic mm,0.547±0.035 gr,0.0006782±0.00001988 ; while in guinea pig was 2.450±0.15 cm, 1.22±0.08 cm,0.2080±0.04 cm,1.174±0.02 cubic mm,0.6418±0.88 gr,0.0017000±0.00021909, respectively , in order. Our finding revealed that the spleen of rabbit was supplied with blood by several numbers of small splenic arteries, which branched from splenic artery (continuous of lineal artery).lineal artery branched from celiac trunk. While in guinea pig the arterial blood comes from splenic artery that arises from celiac trunk directly.
