that assist blood flow throughout the body EXCEPT: -
correct answer ✅vertebral pump
Which of the following definitions, best describes the term
"hemodynamics"? -
correct answer ✅Study of blood moving through the circulatory
system
When discussing or measuring "flow", AKA "volume flow rate", one
would most likely be measuring what and using which units of
measure? -
correct answer ✅discussing the amount of blood flow over a
specified period of time and using a volume unit such as liter
divided by a unit of time such as minute
If a sonographer were to measure flow velocity, he would most
likely record the flow velocity and report it to the physician in which
of the following units of measure? -
correct answer ✅centimeters per second

Referencing the image at the right, what type of flow pattern is
demonstrated? -

Referencing the picture at the right, if this were representing blood
flow through a vessel, which of the following best describes the
conditions of blood flow? -
correct answer ✅narrow, turbulent, changing directions, high
velocity
Referencing the image at the right, what type of flow pattern is

Actual Questions and Answers 2026
Referencing the image to the right, if you were to compare this
river to blood flow through a vessel, which statement best
describes the characteristics that would be found within that
vessel? -
correct answer ✅slow flow, laminar, faster in the middle, slower
along the walls
In order for fluid to flow from one place to another, there must be
a... -
correct answer ✅difference in pressures (pressure gradient)
When the left ventricle contracts, blood leaves the heart with a
particular force or energy, but it immediately begins to lose steam
(energy). What characteristic of blood contributes to this loss in
energy? -
correct answer ✅viscosity
Which of the following results in energy loss as blood moves
through a vessel? -
correct answer ✅friction
Which statement best describes the concept being illustrated by
the diagram to the right? -
, Hemodynamics Weeks 1-5 Exam
Actual Questions and Answers 2026
correct answer ✅The friction along the walls of the vessel results
in an energy loss and a reduction in the velocity of blood cells
moving along the walls while the velocity of flow of the blood cells
in the center of the vessel continue to move more quickly, resulting
in the "bullet" shape.
Using your critical thinking skills, if inertial energy loss occurs when
there is a change in the motion of blood (Newton's Law of Motion),
then in which of the following situations would it be least likely for
an inertial energy loss to occur? -
correct answer ✅steady blood flow
You learned that a pressure gradient (or change/difference in
pressure) is needed for blood to flow. For example, blood moves
from areas of high pressure to areas of low pressure, just as
humans avoid areas of high pressure in their lives and move to
areas of comfort or low pressure.
If the concept is represented by the following:
Pressure Gradient = flow x resistance, what happens to the
pressure gradient if resistance increases? -
