4. 2 anatomical lobes -right and left
Right lobe further divided into caudate lobe on the
posterior surface and quadrate lobe on the inferior surface.
A fold of peritoneum called falciform ligament separates
the right and left lobe anteriorly.

7. Porta hepatis is the fissure on the inferior surface of
the right lobe through which the poral triad which are
portal vein, heopatic artery and bile duct enter the liver.

8. Blood supply
Liver receives about 70% of its blood supply via the
portal vein and 30% from the hepatic artery.
Hepatic artery brings oxygenated blood to the liver
and the portal vein brings food-laden blood from the
abdominal viscera
Hepatic artery divides into right and left branches .
Right branch divides into anterior and posterior
branches.
Left branch divides into medial and lateral branches.

10. There are 3 main hepatic veins which drains into the
Inferior vena cava.
A large central vein runs between the right and left
halves of the liver and receives blood from each.
Then right and left veins which lie further lateral to
the central vein.
11. A Liver lobule consists of hepatic plates that
are one or two cells thick.
Hepatocytes are the principal cells of the
hepatic plates.
Hepatic plates are separated from each other
by large capillary spaces called sinusoids.
Phagocytic Kupffer cells line the sinusoids.
12. Bile is produced by the hepatocytes and secreted
into thin channels called Bile canaliculi located
within each hepatic plate.
Bile drains toward the periphery of the hepatic
plates to the bile ducts, which in turn drain into
hepatic ducts that carry bile away from the liver.
13. Gall bladder is a pouch like organ
attached to the inferior surface of the
liver.
Gall bladder store and concentrate bile.
