1. center of flow with the highest velocity: laminar flow
2. where is the highest velocity in laminar flow?: center
3. with laminar flow, where is the slowest velocity ?: outer layers
4. medium sized vessels and the layers of flow have a narrower range of velocities than laminar flow::
parabolic flow
5. larger vessels (aorta) and all the layers of flow are moving at relatively the same speed:: plug flow
6. where can you find plug flow?: abdominal aorta
7. continuous throbbing or beating: pulsatility
8. what leads to increased pulsatility in arteries?: vasoconstriction
9. vasoconstriction in the extremities leads to pulsatility in arteries and
pulsatility in capillaries and arterioles: increased , decreased
10.what leads to decreased pulsatility in the arteries ?: vasodilation and steno- sis
11.vasodilation and stenosis in the extremities lead to pulsatility in
arteries and pulsatility in capillaries and arterioles: decreased, increase
12.antegrade flow continuous through the entire cardiac cycle: monophasic
13.flow during systole is antegrate and some flow is moving in a retrograde fashion during diastole: biphasic
14.flow during systole is antegrate and using diastole initially some flow moves in a retrograde direction
followed by a small amount of forward flow in end diastole: triphasic
15.The higher the resistance in the vessel, the pulsatile the flow.: more
16.A multiphasic high resistant waveform normally feeds .: extremities
17.A monophasic low resistant waveform normally feeds .: organs
18.Anytime a monophasic waveform is seen in an extremity artery =: abnormal
19.Anytime a multiphasic waveform is seen in an artery supplying an organ
=: abnormal
20.moving forward in the normal direction of blood flow =: antegrade

21. backward flow or filling, or against the normal direction of flow =: retrograde
22.disrupted flow =: turbulence
23.What can turbulent flow be caused by?: stenosis turtuosity
bifurcation post
stenosis
24.abnormal blood flow sound in the heart =: murmur
25.abnormal blood flow sound in a blood vessel =: bruit
26.What can a bruit be caused by?: stenosis, bifurcation, turtuosity
