Arterial Vascularization of Abdominal Region in the Heron (Ardea cinerea)

Two herons provided from Mudurnu region were used in the study. The materials were injected with red-coloured latex through the aorta. A. celiacae originated from aorta abdominalis. A. celiacae was determined as sending the aa. lienalis and continued as the r. dexter a. celiacae and r. sinister a. celiacae. R. dexter a. celiacae was longer and thicker than ramus sinister a. celiacea and it was splitted into the left lobe of hepar, as a. hepatica sinistra, then gave as a. hepatica dextra, a. hepatica sinistra, a. pancreaticoduodenalis, a. jejenualis and a. vesicae biliaris. It was seen that ramus sinister a. celiacae gave several branches to nourish duodenum and a. gastrica sinistra. A. mesenterica cranialis, after appoximately 1.5 cm of a. celiaca’s origin, was determined as coming out from the aorta descendens and except the last part of entrails that was seen to nourish the whole one. R. sinister a. celiaca gave r. dorsalis and r. ventralis. The kidneys were supplied by the a. renalis cranialis and braches of a. ischiadica. After giving a. mesenterica cranialis for rectum, aorta descendens terminated to form a. iliaca externa. The arteriel vascularisations of abdominal region of heron’s organs were examined and differences and similarities obtained were presented herein.
