General info of Liver:
- Liver (Hepar) weights 1,5 kg

Ligamentum Falciforme separates right and left lobe
Two margins:
Inferior border and superior border
Superior border has Area Nauda (bare area), directly in contact with the diaphragm.

Posterior surface:
Right Sagittal groove:
- Formed by fossa for gallbladder and fossa for inferior vena cava
Left Sagittal groove:

Porta hepatis: Common hepatic duct comes out from here.

Ligaments from liver to diaphragm:
- Lig. Falciforme hepatis
- Ligamentum coronaries hepatis
