Right lobe of liver
Encyclopedia
The right lobe is much larger than the left; the proportion between them being as six to one.
It occupies the right hypochondrium, and is separated from the left lobe on its ventral surface by the falciform ligament
; on its posterior surface by the ligamentum venosum
for the cranial (upper) half, and by the ligamentum teres hepatis (aka Round ligament of liver
) for the caudal (under) half. The ligamentum teres hepatis turns around the inferior marging of the liver to come out ventral in the falciform ligament
.
The right lobe is of a somewhat quadrilateral form. Its under and posterior surfaces being marked by three fossæ: the fossa for the portal vein, the fossa for the gall-bladder and the fossae for the inferior vena cava
. These separate the right lobe in two smaller lobes on its left posterior part: the quadrate lobe and the caudate lobe.
