प्रश्न
Why is the velocity of blood flow the lowest in the capillaries?
पर्याय
The systemic capillaries are supplied by the left ventricle, which has a lower cardiac output than the right ventricle.
Capillaries are far from the heart, and blood flow slows as distance from the heart increases.
The total surface area of the capillaries is larger than the total surface area of the arterioles.
The capillary walls are not thin enough to allow oxygen to exchange with the cells.
The diastolic blood pressure is too low to deliver blood to the capillaries at a high flow rate.
