The slow movement of blood through the capillaries allows for adequate molecular exchange between the blood and the tissues. This is essential for the delivery of oxygen and nutrients to the tissues and the removal of waste products from the tissues. If blood passed through the capillaries more quickly, there would not be enough time for this exchange to occur effectively.
