Arteries take blood away from the heart, and veins take blood back to the heart. Usually, blood found in arteries is oxygenated and blood in veins is deoxygenated. The exception is blood traveling from the heart to the lungs and back, when deoxygenated blood travels through arteries to get to the lungs (and be oxygenated) then through veins to get back to the heart.
Capillaries are where veins become arteries (or vice versa). They have very thin walls (only once cell thick), so oxygen can diffuse into the surrounding tissue and waste products (like carbon dioxide) can diffuse in and be removed from the body.

Veins Arteries And Capillaries

Arteries take blood away from the heart (oxygenated or deoxygenated), veins bring blood back to the heart, capillaries are very fine blood vesseslm the blood flows through it one red cell at a time and they connect the arteries to veins.

Arteries=high pressure
Veins = Low pressure
Capillaries are the doorway between the two. They are also the most fascinating. 70% of your blood is in your capillaries. But, only 7% of that actually perfuses or is being used at any given second! Capillaries are dynamic and sensitive. They are critical to your blood pressure and to keeping your vital organs perfused(supplied with blood and nutrients.) Yay for capillaries!!

Arteries take oxygenated blood and distribute it to all of our organs and cells. At the capillaries, is where oxygen goes into the cells and carbon dioxide leaves the cell, this is where the veins come into play. The veins the take the blood with carbon dioxide, or de oxygenated blood through the veins to be expelled out by the lungs. We breath in O2---->left side of heart----->oxygenated blood through the arteries------>exchange O2 and CO2 at the capillaries------->de oxygenated blood through the veins------>through right side of the heart----->to the lungs--------->CO2 leaves the body & O2 comes in

Systemic circulation is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
In the systemic circulation, arteries bring oxygenated blood to the tissues. As blood circulates through the body, oxygen diffuses from the blood into cells surrounding the capillaries, and carbon dioxide diffuses into the blood from the capillary cells. Veins bring deoxygenated blood back to the heart.

VERY SIMPLY PUT: size and function
although this is true, it's not extraordinarily helpful... and I'm blaming this answer on the fact that I just randomly hit a state of smart-azz-ness...
sorry bout that
WEEEEEEEEEEEEEEEEEEEEE!
