Anatomical Description of Liver and intrahepatic Distribution of Hepatic vein and Hepatic portal vein in pigeon (Columbia domestica(

Abstract

This study was carried out to determine the anatomical characteristics of the pigeon liver and the anatomical description of the location of the hepatic portal vein and hepatic vein within the liver, which is to enhance research, whether it be for academic study. The current research was conducted on 12 pigeons of both sexes. The birds were divided into two groups, each one containing six birds. The bird was anesthetized and slaughtered. The two groups were injected with the liquid latex, where the first group was injected into the caudal vena cava, and the second group was injected with latex into the hepatic portal vein. According to the findings of the liver's anatomical analysis, the pigeon's liver is composed of both right and left lobes, is situated in the thoraco-abdominal cavity, and has a red-brown in color. The right vein, transverse portion (the connecting part between the right and left portal vein), and left vein comprised the hepatic portal vein. The hepatic vein is composed of four branches (right, left, middle and umbilical). with slight differences in the number of intrahepatic vein tributaries and the distribution pattern between male and female pigeons.
