Returns nearly all of the venous blood from structures below the diaphragm, but does not drain the gut directly
It forms at L5 from a joining of the common iliac veins. It ascends slightly to the right of the midline (and to the right of the aorta. It pierces the diaphragm at T8 and enters the right atrium
T/F: There are no direct branches of IVC from the gut
R. suprarenal v.drains
directly to IVC
R. gonadal v.drains
directly to IVC
L. suprarenal v. drains to
l. renal v.
the l. gonadal v. drains to
l renal v.
Subcostal v. and lumbar vv. (4 pairs),connected by the vertically-running ascending _____ vein

The left renal vein crosses ____ to the aorta, and passes _____ to the origin of the SMA.
The right testicular/ovarian a. passes _____ to the IVC.
The IVC forms at ____, one level _____ to the division of the aorta
