Liver of 47 yrs old and full term aborted fetus. The liver of both adult and foetus was more extensive, thick at the centre and was gradually thinner towards the periphery.
Weight of adult, liver, 12 kg; of foetus: 1.2 kg.
The parietal surface was convex and was marked by costal impressions. The visceral surface was ireegularly concave which possessed impressions meant for attachment with other different visceral orgfans. The portal fissure was located at the visceral surface near the dorsal border of the liver through which portal vein, hepatic artery and nerves enter or pass out of the organ. The portal fissure did not lodge the bile duct as gall bladder was absent. The hepatic duct was found to emerge out of the portal fissure. The oesophagal notch was not so prominent and the renal impression in caudate lobe was indistinct. The liver was divided at the ventral border into 5 lobes by means of prominent interlobular fissures, viz. right lobe, quadrate lobe, caudate lobe, left medial lobe and left lateral lobe. The right lobe was the largest.
Histological section showed that the liver was muralium simplex. The interlobular connective tissue pattern around the hepatic lobules resembled other domestic animals. The interlobular connective tissue in main trabeculae consisted of mostly collagenous fibers.
