17
Q

Describe the Inferior Vena Cava (IVC).

A

- lies to the right of the aorta

18
Q

What are the main branches of the Inferior Vena Cava (IVC)?

Right atrium

20
Q

What does not have any valves?

A

Inferior Vena Cava (IVC)

21
Q

The Inferior Vena Cava (IVC) will be enlarged due to what?

  • Budd Chiari Syndrome
22
Q

What is Budd Chairi Syndrome?
