What vein is formed by the confluence of femoral and deep femoral veins
Common femoral vein
What is another term for compressibility
Coaptation
What does coaptation mean
To fit together
What are the 4 venous flow patterns
1) spontaneous
2) phasic
3) augment with distal compression
4) augment with proximal release
_________ ________ is where greater/great saphenous joins CFV

Popliteal
The _______ _______ veins terminates in tibio-Peroneal trunk near popliteal fossa
Posterior tibial
The _______ veins terminate into tibio-Peroneal trunk
Peroneal
Flow reversal usually in response to a Valsalva maneuver or during proximal manual compressions indicates ______ _______
Venous reflux
The _______ vein is formed by the confluence of cephalic/ axillary veins
Subclavian
The ______ vein joins with the IJV to form innominate vein bilaterally
Subclavian
The ______ vein is formed by the confluence of the basilic and brachial veins
Axillary
The ______ veins are formed by radial and ulnar veins
Brachial
The ______ and ______ veins are formed by the confluence of palmar arch veins

For lower extremities ______ with expiration and ______ with inspiration
Increases, decreases
For upper extremities ______ with expiration and ________ with inspiration
Decreases, increases
Very sluggish flow seen as herterogenous material moving with respirations and augmentation maneuvers

Budd chiari syndrome
In budd chiari syndrome the primary site of obstruction may be in the
1) hepatic veins
2) sinusoids
3) IVC
