DMS1450 LE Arterial Anatomy & Hemodynamics

Teacher: George Sequeira - BIO1011 Extra Credit
Across
The resting state of the capillary bed in the lower extremities at rest
Describes blood flow when most of the blood cells are moving at the same speed.
Difference between two pressures
The velocity profile characterized by fast-flow components in the center of the vessel that slow as the vessel wall is approached
The expansion and contraction of arteries after each systolic contraction creates this pressure wave
A Doppler waveform that has a thin outline of velocities with an anechoic center
Region in the distal thigh that hides the femoral artery from ultrasound view
Branches of the deep femoral that feed the knee region
Average probe frequency used in the lower arterial exam
Down
When flow increases in the normal lower extremity due to exercise, resistance _________
First branch off the deep femoral artery
Supplies the blood flow with the energy necessary to move blood flow throughout the arterial vascular system
Can suggest arterial stenosis when seen in a Doppler waveform
Difference between two pressures
How is the blood flow related to the cross sectional area of the blood vessel?
A Doppler waveform that has three phases
Blood movement in concentric layers with the highest velocity in the center of the vessel that creates a parabolic flow profile
Hydrostatic pressure is greatest at the _______ due to gravitational pull.
