Arteries, veins and capillaries. Arteries are carry the blood away from the heart, veins return the blood to the heart and capillaries take blood into the smallest tissues and portions of the body. Arteries are thick, ivory and strong, veins are very thin and translucent, capillaries are delicate and small, generally clustered. Hope this helps.

Oh boy....harking back to my dental school anat/physiology courses:
There are elastic arteries, arteries surrounded by muscle tissue, and veins. These are the only three categories I can think of, but my answer very well might be wrong.
Obviously, elastic arteries (such as the aorta) are meant to take blood flow in large volume, and nothing else. Muscled arteries (such as arterioles) are meant to control blood flow to extremities and organs (for various reasons). Veins, in addition to bringing de-oxygenated blood back to the heart, also serve as a reservoir of blood. When the circulatory system becomes hypovolemic, veins constrict, essentially bringing more blood into circulation.
Arteries, as you may know, branch off into arterioles which in turn branch into capillaries--which are porous vessels through which nutrients can be delivered to the tissues and waste products can cross the membranes to be carried off. Capillaries, which are the junction between the "left side" and "right side" of your circulatory system (i.e. oxygenated side and de-oxygenated side, respectively) immediately turn into venules which are tributaries to veins.
Also keep in mind that the lymphatic system drains into the veinous system at some point (perhaps at the superior vena cava--I can't remember).

The three main types of vessels are the heart, the blood vessels(arteries, veins, and capillaries), and the lymphatic vessels. The heart maintains the circulation of the blood. The blood vessels carry nutriment and oxygen to body cells and remove waste pruducts and carbon dioxide. The lymphatic vessels carry the lymph back to the blood.

Atrories, Veins, and cappilaries i think? but if u meen by size I'd go with the aorta, and the superior and inferior vena-cava
