Macroscopic anatomical features of the digestive system in the common buzzard (Buteo Buteo)

Abstract

The study was conducted on 10 bodies of common buzzard (Buteo buteo), from the Association for the Protection of Birds and Nature, MILVUS Group. The bodies were processed according to the dissection protocol established to highlight the macroscopic anatomical features, characteristic of the order in which the studied birds belong. The macroscopic aspect of the esophagus, which is short, distensable, has a well- developed crop, located cranially in the thoraco-abdominal cavity. The glandular stomach and the muscular stomach are poorly developed, joining into the thoracic-abdominal cavity, giving a pear-like appearance. The small intestine is short, divided into the duodenum, jejunum and ileum, and the large intestine has a vestigial, lymphoid type caeca and a short colon. The liver composedof two lobes that join cranially in midline. The right lobe is larger than the left lobe. A well developed gallbladder is located on the ventral side of the right lobe.
