the job of blood vessels is for the circulation of blood around the entire body.
Your blood vessels circulate blood, gases (E.G., oxygen), and nutrients to tissues throughout your body.

Veins - veins run throughout the body, their main job is to deliver deoxygenated blood to the heart so it can get oxygenated and continue circulation. (They are usually are shown as color blue on the models of the circulatory system) Arteries - arteries are body's largest blood vessels. They main job/function is to take the oxygenated blood from the heart and deliver it to the rest of the body.(arteries branch out to capillaries and other smaller blood vessels).(they are usually shown as color red on models of the circulatory system)
it has three kinds of blood vessels because they each have a special job and it helps your body.
The job of red blood cells is to carry oxygen.
Arteries transport Oxygenated blood from the heart all over the body. They carry blood away from the heart. They have thick lumens because the blood inside them is under great pressure as it is pumped away from the heart.
There are three main types of blood vessels:Arteries, which carry blood away from the heart at relatively high pressure.Veins, which carry blood back to the heart at relatively low pressure.Capillaries, which provide the link between the arterial and venous blood vesselsYou can go to: http://www.doctor-dubai.com/dr_info_display.asp?dr_id=24 to get more information.
To carry oxygen
Veins, Arteries (Capillaries are also blood vessels, but the main job is gas exchange).
