Coronary arteries are not veins?

Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins. I got this from wikipedia and I think yes-coronary arteries are veins.they are veins on the heart.

@fairypek your wikipedia answer is correct, but arteries are NOT veins. Arteries are thicker-walled and more muscular than veins, and veins are thin-walled and contain valves, in addition to the different types of blood that they carry (oxygenated, higher-pressure vs deoxygenated lower-pressure).

@gupta.prajjwal The heart is not supplied directly by the blood it is pumping but rather by the coronary circulation. Details here: http://www.biosbcc.net/doohan/sample/htm/vessels.htm
