Chapter 5 venous Anatomy and Hemodynamics Flashcards
What do Deep System veins do?
-Carry majority of leg blood volume
-Run along major arteries of the same name
-Become paired in calf
What are the characteristics of superficial system veins?
Smaller in diameter,
Run close to skin surface,
Have no accompanying arteries
Calf Muscle Veins
Considered part of the deep system,
Drain blood from gastrocnemius and soleus muscles in calf
Perforators
Allow communication between deep and superficial systems,
Normal blood flow should be from superficial to deep
The IVC connects the common iliac vein to:
A left ventricle
B right atrium
C internal common iliac
B right atrium
The SSV arises from the
A GSV
B PTV
C popliteal vein
C pop vein
The calf veno motor pump comprises the
Calf veins,
Skeletal muscle,
Semilunar valves
Which lower extremity vein has the most valves
A CFV
B pop veins
C calf veins
C calf veins, GSV 12, SSV 6-12
During calf muscle contraction which valves close and which stay open?
A distal calf valve closes, Prox calf valve opens, perfs close
A distal calf valve closes to prevent back flow, Prox valve opens and perfs close to prevent back flow
