- except for the bare area
Where is the liver located?
Right hypochondria region
- extends to the epigastric and the left hypochondria region
What is the superior border of the liver?
The diaphragm

2. Visceral
Subphrenic recess
Open space between the liver and the diaphragm
What is it important to know where the liver is? (3)
- Localize an abnormality
