22
Q

Innominate vein is formed by what two veins?

A

subclavian and internal jugular

AKA brachialcephalic

23
Q

The right and left innominate veins come together to form what?

A

the superior vena cava

24
Q

What vein empties the medial aspect of the arm and can be harvested for arterial bypass conduit?

A

basilic

formed by the digital veins

25
Q

Empties the lateral aspect of the arm and can be harvested for arterial bypass conduit?

A

cephalic vein

formed by digital veins

26
Q

What carries blood into sinusoids of the liver with hepato-petal flow and carries approx 80% of blood flow to the liver?

A

portal vein

27
Q

What vein is formed by the superior mesenteric and splenic veins and drains abd part of digestive tract, pancreas, spleen, and gallbladder?

A

portal vein

28
Q

What vein carries blood away from the liver with hepato-fugal flow?

A

hepatic veins

29
Q

Contraction of smooth muscle cells referred to as veno-motor tone, can occur in response to stimulation of the nervous system how?

A

temperature, exercise, stress, and trauma

30
Q

Valves of lower extremities are more susceptible to disease secondary to the effects of what?

A

venous thrombosis

increased ambulatory venous pressure from gravity, increased intrabdominal pressure and/or venous obstruction

31
Q

Veins without valves?

A
  • soleal sinuses
  • common iliac and internal iliac
  • innominate
  • superior and inferior vena cava
32
Q

Veins with valves and the number of valves?

A
  • GSV 12 valves, most below the knee
  • small saphenous 6 to 12
  • each perforators contain a valve
  • infrapopliteal 7 to 12 valves
  • popliteal and femoral 1 to 3
  • external iliac valves 25% of the time
  • common femoral 1
  • jugular 1
  • basilic and cephalic
  • variable number in UE deep veins
33
Q

What is similar about peripheral venous and arterial?

A

resistance

34
Q

True or false, arteries and veins carry the same amount of blood?

A

true

35
Q

What vein shape offers more flow resistance, circular or flattened?

A

flattened

36
Q

The extra-pulmonary veins carry about how much of the blood in the body?

A

2/3’s

37
Q

When distended, the cross-sectional area of the vein is about how much bigger than the corresponding artery?

A

3-4 times

38
Q

The pressure of the veins is determined by the pressure within the vein versus pressure outside the vein, which is what type of pressure?

A

transmural or distended presssure

39
Q

Low transmural pressure results in what type of vein shape?

A

low blood volume results in dumbbell shape

40
Q

What type of pressure is equivalent to the weight of a column of blood pressing against the vessels of the body?

A

hydrostatic pressure

uses the heart as a reference point

41
Q

HP=pgh means what?

A 
p= specific gravity of blood
g= acceleration due to gravity
h= distance from the heart
42
Q

when a patient is supine, the HP exerted on the veins and arteries is what?

A

zero

43
Q

When a patient is standing, what is the HP?

A

gradually increases from level to level down the body reaching 100 mmHg at the ankle
Ankle pressure = circulatory pressure + 100 mmHg

44
Q

When a body part is above the heart, the HP is what?

A

measured less than circulatory
minimum is 0 mmHg dues to vessel collapse
Arm P = circulatory P - 50 mmHg

45
Q

What is the process of the calf muscle pump?

A

a) blood moves from superficial system to deep system
b) competent valves prevent reflux
c) venous volume and pressure decreases
d) venous return to heart increases

46
Q

What is the result when the calf muscle pump is ineffective?

A

a) incompetent valves causes reflux
b) venous volume and pressure increases
c( results in venous pooling and ambulatory venous hypertension

47
Q

What percentage of blood in the legs is forced toward the heart after one calf muscle pump?

A

> 60%

48
Q

What is the result of inspiration?

A

a) decreased in intra-thoracic pressure
b) increases blood flow from upper extremities
c) increases in intra-abdominal pressure
d) decreases blood flow from lower extremities

49
Q

What is the result of exhalation?

A

a) increases in intra-thoracic pressure
b) decreases blood flow from upper extremities
c) decreases in intra-abdominal pressure
d) increases blood flow from lower extremities

50
Q

What is the result of the valsalva maneuver?

A

a) patient takes in deep breath and holds it, then bears down
b) intrathoracic and intraabdominal pressure increases significantly
c) all venous return halted
d) this maneuver equates with proximal compression while preforming Doppler assessment of the lower extremities
