The total cross-sectional area of the capillaries is the greatest; that's why the blood velocity is the slowest through capillaries (this is very important since this is the site of nutrient exchange and you want blood to slow down to allow proper exchange rather than rush past).apillaries have the most area. Its pretty simple. Capillaries carry blood to every cell in the body. Obviously they have the biggest surface area.
There are two types of blood vessels: arteries and veins. Arteries carry blood under high pressure out to all areas of the body after being pumped by the heart. Veins carry blood that should be under low pressure, on its way back to the heart. An artery does not usually connect directly to a vein.Usually there are very small blood vessels called capillaries that connect an artery to a vein..

The capillaries are connected to the smallest veins in the body. The veins get bigger and bigger as they carry the blood back towards the heart.
