Q
Diaphragmatic surface:
A
Smooth, convex
Beneath dome of diaphragm
Posterior aspect: Direct contact with the diaphragm itself ‘bare area’

Visceral surface:
A
Covered by peritoneum EXCEPT fossa of gallbladder & porta hepatis
Irregular
In contact with: right kidney, right adrenal gland, right colic flexure, transverse colon, 1st part duodenum, gallbladder, oesophagus & stomach

Porta Hepatis: Structures entering and exiting the liver
Right and left bile ducts to form common hepatic duct
Right and left hepatic arteries
- Coeliac trunk
- Common hepatic artery
- Hepatic artery proper
Autonomic nerves
Lymphatics
Portal hepatic vein
26
Liver: Vasculature
- Has unique dual blood supply
- Firstly by means of the proper hepatic artery from celiac trunk
- Hepatic portal veins provides blood with partially deoxygenated blood carrying nutrients absorbed from the small intestine = dominant blood supply to the liver
Venous drainage:
- Via hepatic veins
- Central veins of hepatic lobule form connecting veins which then combine to form multiple hepatic veins
- The central veins of the hepatic lobule form collecting veins which then combine to form multiple hepatic veins open into IVC
