Blood Circulation and Hemodynamics Review

These flashcards cover key concepts related to blood circulation, hemodynamics, flow rates, hydrostatic pressure, turbulent flow criteria, spatial resolution, and spatial averaging.

What happens to the flow rate if the vessel lumen doubles while the pressure gradient is maintained constant?

The flow rate will increase by 16 times.

What is the term for the physical principles associated with the study of blood circulation?

Hemodynamics.

What happens to the velocity of blood flow if the area of a vessel increases while maintaining constant flow?

Velocity decreases.

Where is the hydrostatic pressure the highest in a standing patient?

In the ankles.

When does turbulent flow occur in relation to the Reynold's number?

When the Reynold's number meets or exceeds 2,000.

Which factor does NOT affect spatial resolution in the displayed image?

Display Format.

What is spatial averaging?

enhance image quality by combining data from multiple pixels.
