Flow is also called?

• A. Volume flow rate
• B. Velocity
• C. Mass flow
• D. Blood return

Answer: (A)

Flow is the amount of fluid passing through a point per unit time, which is captured by volume flow rate. That’s why volume flow rate is the best fit here—it tells you how much blood moves each minute. Velocity describes how fast the fluid is moving, not how much passes a point per time, and mass flow would be per mass (density matters), which isn’t the standard way flow is described in most physiological contexts. Blood return isn’t a measure of flow at a cross-section. In incompressible fluids like blood, volume flow rate is tied to velocity and cross-sectional area via Q = vA, linking how fast and how wide the path is to the overall amount moving per time.
