Ureters
Urinary bladder
Urethra

2

Where are the kidneys located?

Retroperitoneal in the upper abdomen

3

What is posterior to the kidney?

The diaphragm

4

What is superior to the kidney?

Pleural cavity

5

Which kidney is lower?

Right

6

Where are the superior poles of the kidney?

Right: 11th intercostal space
Left: 11th rib

7

At what vertebral level are the kidneys?

L1

8

Which pole of the kidneys is angled inwards?

Superior

9

Under what ribs is the spleen located?

9 and 10

10

What muscles surround the kidney? Where

Posterior: Psoas major and Quadratus lumborum
Lateral: Transversus abdominis
Superior: Diaphragm

11

What fat surround the kidney? Why?

Perinephric fat
Protection- kidneys have a large blood supply

12

What organs surround the right kidney?

Liver
Hepatic flexure
Hilus
lies behind the second part of the duodenum

13

What organs surround the left kidney?

Stomach
Pancreas
Spleen
Splenic flexure

14

Where does the kidneys blood supply come from and drain to?

From abdominal aorta via the renal arteries
Renal veins drain into inferior vena cava

15

Which renal artery is is longer?

Right

16

Which renal vein is longer?

Left

17

Are the renal arteries or veins posterior?

Arteries

18

What is the renal pelvis?

The funnel-like start of the ureter where fluid drains

19

What structures does filtrate from the kidney flow through to enter the ureter?

Renal papilla
Minor calix
Major calix
Renal pelvis
Ureter

20

What structures are in the cortex of the kidney?

Glomerulus
Bowman's capsule
Arcuate arteries and veins
Proximal and Distal convoluted tubules

21

What is located in the medulla of the kidney?

Loop of Henle
Collecting tubule

22

Are afferent or efferent arterioles larger in the kidney?

Afferent
More goes in than comes out

23

In what plane do the ureters run vertically down the posterior abdominal wall?

In the plane of the tips of the transverse processes of the lumbar vertebrae

24

Where do the ureters cross the pelvis brim?

Anterior to the sacroiliac joint and bifurcation of the common iliac arteries

25

At what level do the ureters enter the bladder?

The level of the ischial spine

26

Where do the ureters get their blood supply?

Renal artery
Testicular arteries
Common iliac arteries
(every major vessel is passes)

27

Where are the constriction points on the ureter?

1) Ureteropelvic junction
2) Pelvic inlet
3) Entrance to bladder

28

How is urine transported to the bladder?

Through the ureters by peristalsis in their smooth muscle walls

29

Where are the sites kidney stones occur in the ureters?

At the constriction points along the ureter

30

Where is the apex and base of the bladder?

Apex points anteriorly
Base points posteriorly
