• phrenic arteries

• pulmonary arteries

• renal arteries

• common iliac arteries

Answer explanation

The inferior phrenic arteries supply the inferior surface of the diaphragm.

There are 3 paired arteries off the abdominal aorta you need to know:

1- inferior phrenic arteries

2-renal arteries

3-common iliac arteries

It's a good tip to learn pairs together.

The paired arteries going to the kidneys are the?

• pulmonary arteries

• renal arteries

• common iliac arteries

Answer explanation

Renal ALWAYS refers to kidney. The renal arteries are red vessels off the aorta & carry oxygenated blood TO the kidneys.

The renal veins are blue vessels carrying DEoxygenated blood away from the kidneys to the IVC inferior vena cava.

The abdominal aorta ends when it branches into the?

• inferior vena cava

• inferior phrenic arteries

• common iliac arteries

• renal arteries

Answer explanation

The common iliac veins are next to the common iliac arteries.

The common iliac veins merge to form the IVC, inferior vena cava.

Name this blue vessel.

• inferior vena cava

• aorta

• common iliac vein
