Blood enters the coronary arteries just above the aortic semilunar valve. After systole (a ventricular contraction), the valve closes. The closing valve causes blood to back flow against the valve. At this time, the backward flow of blood enters into the coronary arteries.
No, veins carry deoxygenated blood back to the heart... Coronary vessels carry blood IN the heart.

Coronary arteries supply blood to the heart itself.
Coronary refers to the blood vessels that supply oxygen-rich blood to the heart muscle. Coronary arteries are essential for the heart to function properly, and blockages or damage to these vessels can lead to serious health problems such as heart attacks.

When people use the word vessel in relation to the cardiovascular system, they usually are referring to blood vessels like arteries, veins, or capillaries. Coronary arteries are specific blood vessels that carry oxygenated blood to the muscles (myocardium) of the heart.
the two blood vessels that carry blood from the body to the heart are the inferior vena cava and the superior vena cava
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 coronary veins.
The coronary circulation refers to the network of blood vessels that supply the heart muscle with oxygen and nutrients. It includes the coronary arteries and cardiac veins. These vessels ensure that the heart receives the necessary blood flow to function properly.
