The velocity of blood flow is quizlet.
What is blood flow velocity? The rate of blood transported per unit time (cm/sec). What is the relationship between total-cross sectional area and blood flow velocity? It is INVERSE. If blood flow velocity is high, total cross-sectional area is low and vice versa. We have an expert-written solution to this problem!
