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.
  The total Cross-sectional area of all the Capillaries in the body is much greater than that of any other set of blood vessels. This gives it a very low Pressure, compair â¦ ed to things like the Arteries and the Aorta, meaning the blood is not being forced out of them as much.The lack of pressure allows the blood to flow fairly slowly which gives time for gas excahnge with the cells of the body.his gives it a very low Pressure, compair â¦ ed to things like the Arteries and the Aorta, meaning the blood is not being forced out of them as much.
