Ch.18 Hemodynamics quiz

The study of blood moving through the circulatory system

The volume of blood moving during a particular time, answers the question "How Much?"

Units for Flow

• Volume / Distance

• Distance / Time

• Volume/ Time

• Volume x Time

The speed or swiftness of a fluid moving from one location to another, answers the question- "How Fast? "

Units for Velocity

• distance x time

• distance / time

• distance / volume

• volume / time

3 forms of blood flow are..

• Phasic

• Steady

• Parabolic

• Pulsatile

Occurs when blood moves with a variable velocity, Blood accelerates and decelerates as a result of cardiac contraction

Pulsatile Flow is most commonly seen in

• Venous Circulation

• Arterial Circulation

• Present when individuals stop breathing

Occurs when blood moves with a variable velocity, blood accelerates and decelerates as a result of respiration

Phasic flow is most commonly seen in

• Venous Circulation

• Arterial Circulation

• Present when the individual stops breathing for a moment
