Function of urinary system: ______ -urine & toxic metabolites from the blood

Elimination

6

Function of urinary system: _______ -salts, glucose, proteins & H20

Conservation

7

Function of urinary system: _______ -blood pressure,hemodynamics & acid-basebalance

Regulation

8

Function of urinary system: ________ -produces Vitamin D, renin, erythropoietin and prostaglandins (hormonal control of other tissues/organs)

Endocrine

9

The _______ is formed from the major calyces

renal pelvis

10

Structures that serve the kidneys (vessels, nerves, and structures that drain urine from the kidney) enter and exit the renal sinus through the ________

renal hilum

11

T/F: The kidney has collateral alarterial circulation.

False; has no

12

In regard to to the vein, artery, and ureter, what is the spatial orientation from anterior to posterior?

Vein, artery, and ureter

13

____ arteries supply the kidneys

renal arteries

14

The renal arteries branch off the aorta at what level of spinal cord

L2

15

Each renal artery divides into ________ arteries that enter the hilum of the kidney

5 segmental arteries

16

How many of the segmental arteries go the anterior portion of kidney and how many go to the posterior portion?

4 anterior and 1 posterior

17

How many segments of the kidney are there?

5

18

Each segmental artery gives rise to a number of ______ arteries, each supplies a renal pyramid

lobar arteries

19

Kidney starts ___ and ____ during development

low and ascends

20

How many major calyces does a kidney typically have?

2

21

____ are muscular tubes (25–30 cm long) with narrow lumina that carry urine from the kidneys to the urinary bladder

Ureters

22

The abdominal parts of the ureters adhere closely to the _______ and are ________ (mesenteric or retroperitoneal) throughout their course.

parietal peritoneum; retroperitoneal

23

They run inferiorly from the apices of the renal pelves at the hila of the kidneys, passing over the pelvic brim at the bifurcation of the common iliac arteries; Theyt hen run along the lateral wall of the pelvis and enter the urinary bladder

ureters

24

The ureters pass _____ the pelvic brim at the bifurcation of the common iliac arteires

over

25

The ureters pass ______ through the muscular wall of the urinary bladder in an _____ direction

obliquely; inferomedial

26

This oblique passage through the bladder wall forms a one-way ______, the internal pressure of the filling bladder causing the intramural passage to collapse

flap valve

27

In addition, contractions of the ______ acts as a sphincter preventing the reflux of urine into the ureters when the bladder contracts

detrusor muscle of the bladder

28

Urine passes down the ureters by means of ________, a few drops being transported at intervals of 12–20 seconds

peristaltic contractions

29

The ureters pass _____ the gonadal vessels

behind

30

T/F: Ureters get their blood supply from the vessels they contact

True
