Part B

The inferior vena cava is medial to the kidneys.

Only the left kidney is retroperitoneal.

The superior surface of each kidney is covered by a lymphatic gland.

The left kidney is lower than the right kidney.

Part C

The ureters __________.

pass anterior to the iliac artery and vein

descend anterior to the gonadal arteries

are found behind the psoas muscles

transport urine away from the bladder

Answer 1

Part A

The left renal vein passes posterior to the superior mesenteric artery
To join the inferior vena cava, the left renal vein courses between the aorta and the superior mesenteric artery. The left kidney vein passes over to Aorta. The left gonadal vein flows into the left kidney vein. The right gonadal vein drains directly into the venal cava below.

Part B

Which of the following correctly describes the position of the kidneys?

The inferior vena cava is medial to the kidneys.

In humans, the kidneys are located high in the abdominal cavity, one on either side of the body, and rest at a strongly oblique angle in a retroperitoneal position.Since the vena cava lies slightly to the right, the left renal vein is longer and travels below the origin of the upper mesenteric artery to the abdominal aorta anteriorly. The right renal artery falls additionally to the lower vena cava.

Part C

The ureters pass anterior to the iliac artery and vein

The ureter exits the pelvis, moving anteriorly to the iliac veins, and typically happens as the common iliac artery is bifurcated into the internal and external iliac arteries.
