how does our heart get its nourishment?
The veins on heart called coronary arteries provides nutrients to heart.
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).
during the blood circulation it gets nourised by the oxygenated blood which also contain nutrients
@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
