CAPILLARIES
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. They are specially designed to allow the movement of substances, mainly gases Oxygen and Carbon Dioxide into and out of the capillary.
VEINS
Veins serve to return blood from organs to the heart. Veins are also called "capacitance vessels" because most of the blood volume (60%) is contained within veins. In systemic circulation oxygenated blood is pumped by the left ventricle through the arteries to the muscles and organs of the body, where its nutrients and gases are exchanged at capillaries, the blood then enter veinules, then veins filled with cellular waste and carbon dioxide. The de-oxygenated blood is taken by veins to the right atrium of the heart, which transfers the blood to the right ventricle, where it is then pumped through the pulmonary arteries to the lungs. In pulmonary circulation the pulmonary veins return oxygenated blood from the lungs to the left atrium, which empties into the left ventricle, completing the cycle of blood circulation.
Capillaries are small blood vessels and they are the end structures of arteries. Their main function is to transport oxygen-rich blood to the body.

All organs have a different structure and function depending on what they are designated to do within the body.
capillaries
The function of the capillaries in the circulatory system is to allow diffusion of wastes, oxygen, and nutrients to the tissues. The rest of the circulatory system is designed to move the blood to the capillaries so they can perform this function.

Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.
