Module 1 Flashcards
The movement and direction of blood flow is know as
Kinetic energy
What must be presented in order for flow to occur
Pressure gradient
Static pressure transformed to dynamic pressure is stated in
Conservation of energy law
What is described as force per unit area
Pressure
Which of the following most influences hydrostatic pressure.
Persons height
If a pressure gradient increases, what happens to flow?
Increases
The amount of fluid moving past a point at a specific time is known as
Volumetric flow rate
If the viscosity of blood increases, hat happens to resistance?
Increases
During systoli, a nonrigid arterial wall will expand. This is known as:
Compliance
If resistance increases, what happens to pressure
Increases
If resistance increases, what happens to flow
Decreases
The pressure at a stenosis is less than the pressure proximal and distal to the stenotic area. This is defined in:
Bernoulli’s Principle
What does the number 2000 represent in the formula for Reynolds number
A turbulent flow
Laminar flow describes flow in
A rigid tube
In Poiseuille’s equation, which of the following factors can have a minimal change in value but results in a large change in flow?
Radius of vessel
