Flashcards in Chapter 21: Venous anatoy Deck (51):
1

venae comitantes

veins corresponding to matching arteries

2

paired peroneal veins

formed by confluence of venules
empty lateral leg

3

paired posterior tibial veins

formed by confluence of venules
empty back of leg

4

paired anterior tibial veins

formed by confluence of venules
empty front of leg

5

popliteal vein

formed by union of ATV and tibial peroneal trunk
becomes femoral vein

6

femoral vein

popliteal vein becomes femoral vein when it passes through adductor hiatus

7

common femoral vein

formed by femoral vein and deep femoral vein joining

8

the common femoral vein becomes

external iliac vein when it passes through inguinal ligament

9

the common iliac vein is formed by

confluence of external and internal iliac veins

10

may thurner syndrome

left common iliac vein passes under right common iliac artery and extrinsic compression happens this can lead to a left lower extremity dvt

11

IVC

formed by confluence of common iliac veins at level of 5th lumbar vertebrae
carries blood into right atrium

12

small saphenous vein (lesser saph)

ascends back of calf
joins popliteal vein

13

what is the longest vein in the body

great saphenous vein

14

great saphenous vein travels

medial to saphenofemoral junction in groin
arises from dorsum of foot

15

perofators

carry blood from superifical veins into deep veins

16

posterior arch vein

has three ankle perforators
plays major role in development of venous stasis ulcers

17

SSV has an important

lateral perforating branch

18

important perforators of posterior arch vein

cockett I II and III

19

intracranial venous sinus

space between dura mater and periosteum that drains blood into the ijv

20

lower extremity venous sinus/ soleal sinus

dilated channels in soleal and gastroc muscle
drain blood into ptv and perov
major part of vald muscle pump

21

paired radial veins

empty lateral hand and forearm

22

paired ulnar veins

empty medial hand and forearm

23

paired brachial veins are formed by

confluence of radial and ulnar veins

24

axillary vein is formed by

confluence of brachial and basilic veins

25

subclavian vein

formed by confluence of axillary vein and cephalic vein

26

innominate vein

formed by confluence of subclavian vein and IJV

27

Superior vena vaca

formed by confluence of right and left innominate veins
carries blood into right atrium

28

Basilic vein

superficial
formed by digital veins
empties medial aspect of arm
can be harvest for arterial bypass
joins brachial vein to form axillary vein

29

cephalic vein

superficial
formed by digital veins
empties lateral aspect of arm
join axillary vein to form subclavian vein
can be harvested

30

portal vein

formed by SMV and Splenic vein
drains abdominal part of difiestic tract
carries blood into sinusoids of liver

31

portal vein carrys how much of blood flow to liver

80%

32

hepatic veins

carry blood from the liver into IVC

33

hepatofugal

away from liver

34

hepatopedal

towards liver

35

renal veins

empty into ivc

36

SVC and IVC terminate where

rt atrium

37

function of veins

thin walled transport blood from capillaries towards heart
carry away waste

38

layers of veins

intima
media (very thin)
adventitia

39

size of veins

capillaries (small)
vena cava (largest)

40

venous valves are an extension of

intimal layer

41

venous valves are

biscuspid structure providing unidirectional flow

42

valves of lower extremities are

more susceptible to disease secondary to effects of venous thrombosis

43

veins without valves

soleal sinuses
external iliac vein
common iliac
internal iliac
innominate
SVC and IVC

44

external iliac vein can contain valves

25% of the time

45

great saph # of valves

12 mostly below knee

46

small saph # of valves

6-12

47

perforators # of valves

each contain a valve

48

infra popliteal veins # of valves

7-12 each

49

popliteal and femoral valves

1-3 each

50

common femoral vein valve #

1

51

IJV valve number
