The velocity of blood flow is lowest in capillaries because:
A. The capillaries walls are not thin enough to allow oxygen to exchange with the cells.
B. The capillaries are far from the heart and blood flow slows as the distance from the heart increases.
C. The diastolic blood pressure is too low to deliver blood to the capillaries at a high flow rate.
D. The total cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other part of the circulatory system.

The velocity of blood flow is lowest in capillaries because: The total cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other part of the circulatory system. The correct option is D.

Blood flow velocity and total blood vessel cross-sectional area are inversely related. The velocity of flow reduces as the vessels' overall cross-sectional area grows. The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients.

Therefore, "The overall cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other portion of the circulatory system" is the right response.
