Why is the velocity of blood flow the lowest in the capillaries?

A

The systemic capillaries are supplied by the left ventricle, which has a lower cardiac output than the right ventricle.

B

Capillaries are far from the heart, and blood flow slows as distance from the heart increases.

C

The total surface area of the capillaries is larger than the total surface area of the arterioles

D

The capillary walls are not thin enough to allow oxygen to exchange with the cells.
