  • Length: 10-11 cm (left kidney slightlylonger)
  • Width: 5-6 cm (left kidney slightlynarrower)
  • Thickness: 2.5-3 cm
  • Surfaces: Anterior & Posterior
  • Borders: Lateral (convex) & Medial (concave)
  • Poles: Upper (superior) & Lower (inferior)
  • Weight: 150g (male), 135g (female)
  • Hilum: On Medial Border

2

What makes up the renal lobe?

Renal Lobe = Medullary Pyramid + Surrounding Cortex

3

Identify the vascular supply:

  1. Renal Artery
  2. Segmental Artery
  3. Lobar Artery
  4. Interlobar Artery
  5. Arcuate Artery
  6. Interlobular Artery

4

How much of the cardiac output is supplied to the kidneys?

Renal arteries: supply the kidneys with 20-25% of the cardiac output

5

Which artery branch from the renal vascular supply is the first to penetrate renal tissue?

D. Interlobar artery

6

What is the location of the kidneys?

  • primarily retroperitoneal and adjacent to the posterior abdominal wall
  • located between vertebral levels T12-L3

7

Which kidney sits higher than the other?

left kidney sits a few centimeters higher than the right kidney (because of the liver)

8

Identify the levels of sympathetic innervation for the following:

  1. Kidney
  2. Ureter
  3. Urinary Bladder

  1. Kidney: T10 - L1
  2. Ureter: T11 - L2
  3. Urinary Bladder: T11 - L2 

9

How does the urinary system receive parasympathetic innervation?

Mostly via:

  1. Vagus nerve
    • ​​kidney and ureter
  2. Pelvic splanchnic nerves
    • ​ureter and bladder

10

Posterior Relations of the Kidneys:

  • Green = Respiratory Diaphragm
  • Salmon = Transversus Abdominis Aponeurosis
  • Yellow = Quadratus Lumborum
  • Purple = Psoas Major

11

What helps hold the kidneys in place as the body moves around (breathing, walking, adjusting posture)?

perirenal fat

12

Blood supply of the ureter comes from ...

branches of arteries encountered along its course from kidney to urinary bladder
