Q

how is the radial veins formed by?

A

confluence of venules

24
Q

how does the radial veins empty?

A

empties lateral hand and forearm

25
Q

how is the ulnar vein formed?

A

confluence of venules

26
Q

how is the brachial vein formed?

A

confluence of radial and ulnar

27
Q

how is the axillary vein formed?

A

confluence of brachial and basilic vein

28
Q

how is the subcl vein formed?

A

confluence of axillary and cephalic vein

29
Q

how is the innominate vein formed by?

A

confluence of subclav v and IJV (also called brachiocephalic)

30
Q

how is the SVC formed by>

A

formed by confluence of right and left innominate veins

31
Q

where does the SVC carry blood too?

A

right atrium

32
Q

how is the basilic vein formed by?

A

formed by the digital veins

33
Q

how does the basilic vein empty?

A

empties medial aspect of arm

joins brachial vein to form axillary vein

34
Q

what veins can be harvested for arterial bypass conduit?

A

bascilic and cephalic

35
Q

how is the cephalic vein formed by?

A

formed by digital veins

36
Q

how does the cephalic vein empty?

A

empties lateral aspect of arm

join axillary to form subclavian v

37
Q

what does the SVC drain?

A

drains head and upper extremity veins

38
Q

what are the central veins?

A

SVC
IVC
Portals
Renal

39
Q

what does the IVC drain?

A

lower half of body

40
Q

how is the portal vein formed?

A

SMV and splenic veins

41
Q

what does the portal vein drain?

A

drains abd part of digestive tract, panc, spleen, and GB

42
Q

where does the portal vein carry blood too?

A

carries blood into sinusoids of the liver

has hepatopetal flow

43
Q

What percetage of blood does the portal vein carry?

A

80%

44
Q

what do hepatic veins carry blood to?

A

carries blood from liver into IVC (hepatofugal flow)

45
Q

the renal veins where do they empty into?

A

IVC

46
Q

what is the function of the veins?

A

thin walled collapsible tubes that transport blood from capillaries toward heart
carry away waste products of cellular activity

47
Q

what are layers of the veins?

A

intima, media, adentitia

48
Q

which layer of the veins is the thinnest?

A

media

49
Q

where does the venous system start?

A

at capillaries

with progressive increase in size (venules smalles, vena cava largest)

50
Q

what is veno-motor?

A

have some element of reactivity

51
Q

what can occur in response to stimulation of sympathetic nervous system

A

contraction of smooth muscle cells

52
Q

what are some examples of stimulation of sympathetic nervous system?

A

temp
exercise
stress
trauma

53
Q

what are venous valves?

A

extension of intimal layer

bicuspid structures providing uni-directional flow

54
Q

why are valves of the lower extremities more susceptible to disease

A

secondary to the effect of venous thrombosis, increased ambulatory venous pressure from gravity, increased intrabdominal pressure and venous obstruction

55
Q

what are the veins without valves?

A 
soleal sinuses
EIV - contains about 25% of the time
CIV 
IIV 
innominate
SVC
IVC
56
Q

what are veins with valves?

A 
GSV -apprx 12 most below the knee
LSV 6-12
perforator- each contain a valve
infrapop (deep veins) 7-12
pop and femoral 1-3 
EIV - 25% of the time
CFV -1 
jugular vein -1 
basilic and cephalic 
variable number in UE deep veins
