17
Q

Describe the Inferior Vena Cava (IVC).

A

- lies to the right of the aorta

18
Q

  • common iliac veins
19
Q

The Inferior Vena Cava (IVC) enters the heart via the what?

Right atrium

20
Q

What does not have any valves?

A

Inferior Vena Cava (IVC)

21

22
Q

What is Budd Chairi Syndrome?
