Flashcards in NBDE ANATOMICAL SCIENCES Urinary System Deck (42):
1

the ureter connects which of the following parts of the kidney to the urinary bladder:
a. renal papilla
b. renal columns
c. renal calyx
d. renal pelvis

renal pelvis

2

kidneys are located at the back of the abdomen one on each side of the spine at the level of the

lower ribs on the sides of the lumbar spine

3

two hormones the kidneys secrete

renin and erythropoietin

4

the kidneys lie retroperiotoneally = ?

external to the peritoneal lining of the abdominal cavity in front of the muscles attached to the vertebral column

5

the outer light brown layer of the kidneys, the cortex contains

glomeruli, proximal and distal convoluted tubules

6

the site of blood filtration in the kidneys are the

cortex

7

the inner dark-brown layer of the kidneys contains

cone like renal pyramids separated by renal columns

8

renal columns are extensions of the

cortex

9

___ = a hollow inner structure that joins with the ureters and receives urine thru the calyces

renal pelvis

10

the ureters are tubes that connect the

bladder to the kidneys, take urine to them

11

renal ___ is the apex of the pyramids. this is where the collecting ducts pour into minor calcyes

papilla

12

Renal __ is an extension of the renal pelvis. minor calyces unite to form major calyces, which urine is emptied into

calyx

13

__ is a cavity within the kidney which is occupied by the renal pelvis, renal calyces, blood vessels, nerves and fat.


renal sinus
Contents of renal sinus are

1 renal vein
2 renal artery
3 renal pelvis
"VAP"

14

which kidney lies slightly lower than the other? and why

the right kidney lies lower bc large size of the right lobe of the liver

15

each kidney is surrounded by a _ and is supported by adipose tissue

fibrous renal capsule

16

each kidney has an indentation, the __ on the medial border through which the ureters, vessels and nerves enter and leave

hilum

17

each kidney receives blood from _ artery, a branch of the _

renal artery
abdominal aorta

18

the renal corpuscule contains

glomerulus (network of parallel capillaries) and a double walled cup, the Bowman's capsule = site of filtration

19

the filtrate is normally free of 2 things

cells and proteins

20

macula densa is an area of closely packed specialized cells lining the wall of the _

distal tubule

21

the macula densa cells are sensitive to concentration of

NaCl

22

how does the macula densa respond to a decrease in sodium chloride

decrease resistance to blood flow in afferent arterioles = increases glomerular hydrostatic pressure and helps return GFR to normal and increases renin release from juxtaglomerular cells of the afferent and efferent arterioles

23

the collecting ducts descend into the medulla where they converge to produce large diameter ducts in the papillae called the

papillary ducts or ducts of Bellini

24

the papillary ducts or ducts of Bellini open into the __ at the tip of the papillae

calyces

25

which of the following persists as the definite (permanent) kidney:
a. pronephros
b. metanephros
c. mesonephros
d. none of the above

b. metanephros

26

urinary system parts are

kidneys ureter urethra and bladder

27

the kidney develops thru phases each marked by the development of a more advanced kidney. what are they

pronephros, mesonephros, and metanephros

pronephros = most immature form of kidney and metanephros is the most developed

28

is the left or right ureter longer

left is longer bc the right kidney is lower due to liver.

29

the ureters are narrowest

near origin at renal pelvis = ureteropelvic junction

30

the ureterovesical junction is

bw the ureter and bladder

31

filling of the bladder constricts the ureters at the _ junction

ureterovesical

32

peristaltic waves moves urine into the ureters every 1 to 5 min. T/F

true

33

in the female the ureter descends _ to the ovary

posterior

34

the urinary bladder is in the_ cavity

pelvic

35

the urinary bladder is slightly lower in F or M

female

36

_ epithelium lines the urinary bladder

transitional

37

the urinary bladder _ urine

concentrates urine and is a reservoir of urine

38

the bladder discharges thru

the urethra

39

transition epithelium cells of the bladder are specialized to change shape in response to

pressure

40

when the bladder is empty, bladder transitional epithelium cells are _ shaped

less cuboidal = empty


as the bladder fills = compressed and flattened

41

in males the urethra carries

semen and urine

42

the portion of the male urethra that passes thru the urogenital diaphragm is called the

membranous urethra
