Flashcards in anatomy of kidney Deck (48):
1

What kidney sits lower than the other

Right sits lower than left

2

What is the level of the kidneys

T12/13

3

How many supporting tissue layers surround each kidney

3

4

name the 3 supportive layers

renal fascia, renal capsule and adipose capsule

5

describe the renal capsule

A thin fibrous sac made of irregular tissue that maintains the kidney shape and protects it from trauma

6

Describe the adipose capsule

layer of fat that surrounds renal capsule. Protects and supports kidney

7

Describe the renal fascia

Anchors kidneys to the peritoneum and posterior wall. Provides kidney anchorage

8

What is the renal cortex

the outer layer of the kidney

9

what is found at the renal cortex

glomeruli

10

what occurs at the renal cortex

ultrafiltration

11

What type of arteries are found in the renal cortex

arcuate and inaccurate arteries ad veins.

12

What type of nephrons are found in renal cortex

cortical nephrons

13

What is the renal column an extension of

the renal cortex

14

what is the function of the renal column

to anchor the renal cortex

15

What part of the kidney is the renal medull

The inner section

16

What structures are found in the renal medulla

renal pyramids

17

Why does the renal medulla appear striated

parts of loop of hence
collecting tubules of cortical nephrons
tubular system of juxtamedullar nephrons

18

Where do renal calyces empty into

renal pelvis and ureter

19

what are the 2 types of calyces you can get

major and minor

20

what is the pathway of urine?

Real pyramids drain into minor and major calyces, drain into renal pelvis, empties into ureter

21

What do minor calyces surround

renal pyramids

22

What forms a major calyce

many minor calyces

23

what forms the renal pelvis

many major calyces uniting

24

Why are renal pyramids striated

due to nephron loops and collecting tubes

25

where do renal pyramids terminate

in minor calyce

26

Whatare renal papilla

Tips of renal pyramids that protrude into minor calyce

27

where is the renal pelvis located

at the hilllium

28

what is the function of renal pelvis

collects urine from major calyces and drains to the ureter

29

Describe a juxtamedullary nephron

long loop of henle

30

what 2 types of nephrons can you get

cortical and juxtamedullary

31

What are the functions of nephrons

to perform osmoregulation and remove waste from the body

32

Describe a cortical nephron

short loop of henle

33

Describe a cortical nephron

short loop of henle

34

name the 2 parts of a nephron

renal corpuscle and renal tubule

35

what does the renal corpuscle surround

the glomerulus which is surrounded by the bowman capsule

36

What isthefunction of renal tubule

connects to collecting ducts that collect urine

37

describe the pathway of renal veins

Interlobular
arcuate
interlobar
renal

38

Describe the pathway of renal arteries

renal
segmental
interlobar
arcuate
interlobular

39

describe renal capilarries

interlobular artery enters the cortex where it divides into branches called afferent arterioles. Each nephron receives an arteriole. Arteriole divides to form a plexus

40

Name some functions of the kidney

regulation of osmolarity, regulation of ion conc., produces hormones, excretion of toxins/water

41

draw and describe the loop of henle (nephron structure)

k

42

draw structure of kidney

f

43

Draw and explain the loop of henle

d

44

Where does glucose resorption occur

the proimal tube

45

What part of bladder controls voluntaary urination

external urethral sphincter controlled by the pudenal nerve

46

Define dysplasia

When cells become abnormal

47

Define metaplasia

Abnormal change in tissue number

48

What epithelia is present in the bladder

transitional
