Answer 11

Energy Gradient

Question 12

Energy that a body possesses by virtue of being in motion

Answer 12

Kinetic energy

Question 13

Pressure is defined as force per unit area

Answer 13

Pressure (energy)

Question 14

Potential energy associated with the gravitational feild

Answer 14

Gravitational energy

Question 15

V = friction existing between contiguous layers of fluid
F = of or produced by the action of one surface or object rubbing against or moving over another
I= Mass is an objects resistance to acceleration or flow

Answer 15

Energy loss in circulation (frictional, Viscous, Inertial stenosis)

Question 16

Produces disturbed or turbulent flow

Answer 16

Effects of stenosis

Question 17

Fluid moves against a pressure gradient from a point of low pressure to a point of high pressure

Answer 17

Bernoulli’s princeple

Question 18

Fluid in a tube flows in response to a pressure difference at both ends

Answer 18

Pressure flow relationship

Question 19

The voltage in a circuit equals the product of current and the resistance

Answer 19

Ohm’s law

Question 20

The pressure that the fluid exerts on the walls of it container

Answer 20

Hydrostatic pressure

Question 21

Inspiration = diaphragm contracts expands greater volume
Expiration = passive relaxation rib sternum back in regular position

Answer 21

Venous and breathing flow

Question 22

Go from one place to another in a steady stream

Answer 22

Flow

Question 23

Narrowing of a vessel lumen produces disturbed or turbulent flow

Answer 23

Stenosis
