they are inversely proportional (increasing area decreases velocity) therefore in large vessels like the vena cava, blood has a low velocity blood also has a low velocity in the capillary beds, because of the increased cross-sectional area produced by many capillaries.
Blood flows slower in veins than arteries because veins have valves. Veins carry deoxygenated blood back to the heart, whereas the heart pumps oxygenated blood through the art â¦ eries to the body. Because it is going to the whole body, this blood needs to be at a high speed and under lots of pressure.
