And if they are the same thing, arteries are defined as the vessel from which blood leaves the heart... And so...?
erm, possible to give links so I'll understand better?
Thanks guys! =)

arteries carry blood from the heart while veins return blood to the heart.
Coronory arteries carry oxygenated blood to the heart muscle itself - in effect the blood they carry is pumped FROM the heart to itself to keep its own muscle supplied with oxygen and nutrients and remove carbon dioxide.
The pulmonary vein brings oxygenated blood from the lungs back to the heart from where it is pumped round the body.
The cycle of blood pumping is:
HEART > pulmonary artery > lungs [picks up oxygen, discharges carbon dioxide] > pulmonary vein > HEART > aorta (the main artery) > other arteries (including coronary artery) > capillaries in the body tissues [discharges oxygen, picks up carbon dioxide] > veins > vena cava (main vein) > HEART > (cycle repeats)

The coronary arteries are the arteries around the heart that feed it oxygen. They are the ones that get blocked and caused heart attacks. The pulmonary vein is the vessel that leaves the lungs with oxygenated blood and goes to the left side of the heart in order to pump the oxygenated body to the body. The pulmonary vein is the only vein that carries oxygenated blood.

A lot of confusion exists because it is a general rule that arteries carry oxygenated blood and veins carry deoxygenated blood. This is reversed in the pulmonary arteries due to the fact that oxygen uptake takes place in the lungs, so blood in the pulmonary artery is deoxygenated and blood returning to the heart from the lungs in the pulmonary veins is oxygenated.

They are not the same. The coronary arteries are around the heart and supply blood to the heart muscle itself while the pulmonary vein supplies the oxygenated blood to the heart (to be pumped).

First, a definition: Arteries don't have to actually leave the heart, they just carry blood away from the heart.
Now:
Pulmonary veins: Carry blood from the lung back to the heart.
Coronary Arteries: Carry blood from the aorta to the heart, to give the heart the blood it needs to live.

in general arteries carry oxygenated blood from the heart and veins carry de-oxygenated blood to the heart. however the pulmonary vein carries oxygenated blood to the heart from the lungs and the pulmonary artery carries de-oxygenated blood from the heart to the lungs.

no
Coronary arteries on directly on the surface of the heart muscle, and provide the muscle with its blood supply.
Pulmonary vein is the large blood vessel that returns oxygenated blood from the lungs back to the left atrium of the heart.

In arteries, blood flow away from the heart.
In veins, blood flows to the heart.
