326 Kidney

Coronal section through right kidney and suprarenal gland

(posterior aspect). The renal pelvis has been opened and the fatty

tissue removed to display the renal vessels.

Right kidney (posterior aspect). Partial coronal section to expose

internal aspect of the kidney.

Cast of renal pelvis and calices.

1–4 = Renal segments on anterior surface.

1 Renal vein

2 Renal artery

3 Renal pelvis

4 Abdominal part of ureter

5 Major renal calyx

6 Cribriform area of renal papilla

7 Cortex of suprarenal gland

8 Medulla of suprarenal gland

9 Cortex of kidney

10 Medulla of kidney

11 Renal papilla

12 Minor renal calyx

13 Renal sinus

14 Renal columns

15 Fibrous capsule of kidney

Each kidney can be divided into five segments

supplied by individual interlobar arteries

known as end arteries. Thus, obstruction leads

to infarcts marking the trace of segment

borders. The anterior kidney surface reveals

four segments; the posterior, only three (Nos.

1, 4, and 5).

Left kidney (arteriography).

The kidneys are perfused by app. 1.500–1.800 l of blood per

day via the renal arteries. Out of more than 1.2 million

renal corpuscles (glomeruli), 1% of this volume (id 150–180 l)

is filtered as a cell free fluid. In the tubular system, 99% of

this fluid, together with useful substances like glucose and

ions, are reabsorbed. Only 1–1.5 l of urine containing waste

material is excreted.

Diseases of the renal vascular system may impair the filtering

process and thereby the composition of the blood.
