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.
Capillaries are the smallest of all blood vessels and form the connection between veins and arteries. As arteries branch and divide into arterioles and continue to reduce in size as they reach the muscle they become capillaries. Here the capillaries form a capillary bed, which is a vast expanse of very small vessels forming a network throughout the muscle. However, unlike veins and arteries, their main function is not transporting blood.
