European ground squirrel is the only representative of its genus in Serbia. It is used as experimental animal in microbioogy, parasitology, pharmacology and immunology. The objective of this work was to investigate a part of cardiovascular system of ground squirrel so in that way to contribute to a better knowledge of this animal body structure and accordingly to comparative anatomy in general. The investigation included 6 ground squirrels, of both gender, body weight 200-300 grams. For obtaining the liver arterial vascularization, after exsanguination of the animal, contrast mass of gelatin coloured with tempera was injected into abdominal aorta (Aorta abdominalis). After injecting, the blood vessels were prepared and photographed. In ground squirrel A. celiaca is odd, larger vessel that exits the abdominal aorta. It is divided into three branches: A. lienalis, A. gastrica sinistra and A. hepatica. A. hepatica is divided into A. hepatica propria and A. gastroduodenalis. A. hepatica propria further gives A. cystica, Rami cardiaci and small branches for Lnn. portales. A. gastroduodenalis is divided into A. pancreaticoduodenalis and A. gastroepiploica dextra. A. celiaca in nutria and rat is an odd artery, divided into A. lienalis, A. gastrica sinistra and A. hepatica. In rabbits, celiac artery (A. celiaca) is divided into A. lienalis and short trunk from which A. gastrica sinistra and A. Hepatica emerge. A. celiaca in golden hamster does not exist in the form of tripus coeliacus (A. lienalis, A. gastrica sinistra and A. hepatica), but from A. celiaca it is firstly separated A. hepatica, and then short trunk from which A. gastrica sinistra and A. Lienalis emerge. In guinea-pig, from abdominal aorta a joint tree branches off into A. celiaca and A. mesenterica cranialis (Truncus celiacomesentericus). Based on the above mentioned results, it can be concluded that A. celiaca in European ground squirrel, nutria and rat branches from abdominal aorta as a separate blood vessel. In these animals A. celiaca branches are: A. lienalis, A. gastrica sinistra and A. hepatica.
