1. Acute thrombus: newly formed clotted blood within a vein, generally less than 14 days old
2. Chronic Post thrombotic changes: Residual material present within a vein for a period of several weeks or
months; also called chronic change, scarring
3. Deep vein: a vein that is the companion vessel to an artery and travels within the deep muscular compartments of the
leg
4. Perforating vein: A small vein that connects the deep and superficial venous systems; a vein that passes between the
deep and superficial compartments of the leg
5. Superficial vein: A vein that is superior to the muscular compartments of the leg; travels within superficial fascial
compartments; has no corresponding companion artery.
6. Valve: an inward projection of the intimal layer of a vein wall producing two semilunar leaflets; which
prevents the retrograde movement of blood flow
7. Where do veins originate?: at the venous side of the capillaries as venues
8. T/F as blood flows through the high pressure arterial system of the arteri- oles, arterioles and capillaries, it
loses pressure as it moves ?: true
9. are veins low or high pressure?: low
10.what is the pressure of the vessel when blood enters the venules?: -
15mmHg
11.what is the pressure of small veins ?: 6mmHg
12.what is the pressure of large veins ?: 2mmHg
13.what is the pressure of the SVC/IVC by time blood enters?: 1mmHg
14.Veins carry blood, and empty into the .: deoxygenated, RA
15.The deep system carries % of blood out of the limb.: 85-90%
16.direct pathway to the heart =: deep system
17.What compartment does the deep system lie in?: muscular
18.Do deep systems veins have an artery with the same name?: yes
19.Regulates body temperature =: superficial system

20.What compartment does the superficial system lie in?: superficial
21.What does the superficial system empty into?: deep system
22.connects superficial to deep system =: perforating system
23.The perforating system should flow from to system.: unidirec-
tionally, superficial, deep
24.How many perforators should each leg have?: 100
25.what is the primary function for veins?: return blood to the heart, reservoir for blood
26.How much blood volume resides in the venous system?: 2/3
27.Is the venous system a low or high pressure system?: low
