Energy

Question 1

movement of any fluid medium between two points requires two things

Answer 1

pathway along which the fluid can flow

pressure differential

Question 2

amount of flow depends upon

Answer 2

energy difference : includes losses resulting from fluid movement

any resistance which tends to oppose such movement

Question 3

Low Resistance=

Answer 3

higher flow rate

Question 4

High resistance=

Answer 4

lower flow rate

Question 5

total energy contained in moving fluid is the

Answer 5

sum of pressure, kinetic, and gravitational energy

Question 6

pressure (potential/stored) energy

Answer 6

stored energy (release when walls recoil
major form of R for circulation of blood
expressed in mmHg

Question 7

Kinetic energy (velocity)

Answer 7

small for circulating blood

expressed in terms of fluid density and its velocity measurements

Question 8

gravitational energy

Answer 8

hydrostatic pressure

Question 9

hydrostatic pressure is equivalent to the

Answer 9

weight of the column of blood extending from the heart to level where pressure is measured

Question 10

what is needed to move blood from one point to another

Answer 10

energy gradient

Question 11

relates to the tendency of a fluid to resist changes in its velocity

Answer 11

inertia

Question 12

as the blood moves farther out to periphery, energy dissipated largely in the form of

Answer 12

heat

Question 13

energy continually restored by

Answer 13

pumping action of heart
