Editing Liver (section)

=== '''Coverings''' ===

** Fibrous capsule of Glisson
** Capsule invaginated by each      portal triad at the hilum, forming a portal pedicle surrounded by a      fibrous sheath (sometimes called valoean sheath)
*** Within each sheath the PV       is surrounded by loose areolar tissue - dissection is relatively easy
*** Condensation of tissue       around artery and duct is denser and tougher
*** Within the sheath, the bile       duct tends to be elliptical rather than round, and inferior aspect       usually faces the corresponding artery, and is always close to it
*** PV tends to lie posterior       to the bile duct and hepatic artery
*** The sheath can be mobilised       and ligated as a whole from within the liver substance - often easier       and safer
** Visceral peritoneum (apart      from GB fossa, porta hepatis and two wedge-shaped areas on either side of      the IVC)
** Bare area - area between the      coronary ligaments/triangular ligaments which is not covered by      peritoneum. See below under 'coronary ligament'.
